This might not be the best answer, but at least it worked. I'v downloaded the plugin directly, and found out where are the plugins installed. Unziped it and copied there.

I opened Android Studio and I was able to see the KMM plugin. I then got an error about KMP being incompatible in K2 mode and I just went to Settings searched for K2 mode, and unchecked it.

I believe I restarted my Android Studio and ran the app and it seemed to work. I'll later do more work on the app and check if everything's actually running properly.
