How can I add a top texture to a block? 1.18.1

[Leventeand1]

Hello! Hello! Yesterday I got myself to try to make a minecraft forge mod and it worked. I got as far as putting a block in the mod. When I got there I made the model.json file and I wanted to make a block of grass. It has a side texture and a top, right? I can't do it, to have a different texture on the top and on the side. Can someone help me please? (1.18.1)
