I have seen many videos with the 2.4l engine, can you find out for me where the fill plug is located on top and whether it is the same as the 2.4l one?

Always use Acura Automatic Transmission Fluid (ATF Type 3). Using the wrong type ATF can affect shift quality. Check out the images (below). Let us know if you need anything else.

I don't think the fill plug is on side by axle like it's showing. I see the drain plug which is an Allen key type on bottom. But the oil should be on top
