Can’t add Avatar Descriptor

Hey everyone. I wanted to upload an avatar, however, I can’t seem to be able to add the VRC Avatar Descriptor? I went to component>scripts>VRC.SDK3.Avatars.Components, but the option to add a VRC Avatar Descriptor is greyed out.
Also, the Components>Add is greyed out as well.

I don’t know what I’m doing wrong, so any help is really appreciated!

Is the SDK already mounted in your unity?

are you using the most recent version of unity?

furthermore can you post a screenshot of your projct so we can hlp you out easier.

Hello! I forgot to edit/reply to this topic, but I actually figured out what’s wrong. I ended up not using the right version of unity, and I also, for some reason, didn’t drag the mode into the scene.
Thank you for your help, by the way! : )

Well there we go!

Enjoy your avatar!
