The name of the queue is Low Quality Posts, not VLQ (Very Low Quality).
Posts sent to this queue include those flagged as NaA (Not an Answer), and since the VLQ flag is of limited use (where it applies, the NaA flag may generally be reasonably applied anyway), posts in this queue are far more likely to have been flagged as NaA than VLQ.
I believe, though I may be wrong, that posts flagged as Spam or as Rude/Abusive are also sent to the Low Quality Posts queue, although they are likely to be deleted before they reach the queue by the flags themselves or by moderators.
See How do I flag correctly? for guidance on flag usage.
As explained in the linked post, VLQ only applies when the post cannot be salvaged by editing, meaning that it does not make any sense at all. If the post seems not to be an attempt to answer at all, or seems not to be an answer to this particular question (it misunderstands or misses the point of the question), then it is flaggable as Not an Answer.
At first reading, the post in question seems to attempt to answer the question asked, so seems not to be flaggable as NaA. However, it lacks detail, since it doesn't explain how to do what it suggests. This means that it could be improved by editing (what is being suggested is certainly clear). That means that the VLQ flag does not apply.
If you know how to improve this post to make it substantially more useful as an answer to this question, you can choose Edit. That will complete the review, immediately removing the post from the queue, and resolving the flag as helpful, as the system will consider the post to have needed fixing and to now be fixed. (If you want to make superficial edits to the post like fixing formatting, and you are not sure whether it should be deleted or not, you can click the link to the right of the post in review and edit it outside of the queue to avoid completing the review.)
If you think an answer should be deleted, you can Recommend deletion or Delete in this queue. See Why and how are some answers deleted? for guidance. If you do not think the post should be deleted, but you cannot edit it to improve it yourself (perhaps it does not need improvement at all), you should vote Looks OK, leaving a comment for the author on how to improve if it seems helpful to do so.
In this case, I think the post is neither VLQ nor NaA and should probably not be deleted. I don't know how to edit this post, so I would probably vote Looks OK and perhaps advise the author to add some more details.
Also, since I don't have much experience in the topic and unsure whether this answer was really useful, I might simply Skip the review. It's always fine to do this. The skip button is your friend. When you are unsure, let someone who knows better deal with it.
If you are not sure whether the post qualifies for deletion, or you think that it does not, but you still think it is of low quality, you may follow the link to the post and downvote it. This post seems possibly worthy of downvoting to me. If the answer seems to be an answer, but seems to you to be wrong or misleading, you should definitely downvote it.
Also note that although we cannot downvote directly from the queue, downvoting posts that should be deleted is helpful, because it makes it easier for users with >20k reputation to cast delete votes on the post, and makes it more likely that people will notice it and flag it or vote to delete it.
If, on the other hand, you feel the post is actually a useful answer (as it is, or after your edits to it), you should upvote it :)
