First, congrats-
There's really no need to transfer it to a secondary. That's old advice that has been debunked in the past few years. However, do give it time to clear and for the yeast to post-process the fermentation byproducts that are still in the beer. For most batches, that takes about 2 weeks.
The key thing to remember is that the yeast work on their schedule, not yours, and even if the airlock activity has essentially stopped, there is still stuff going on that you can't see.
If you remain patient and give them the time that they need, you will be amply rewarded.
HTH-
