RA won't recognize iMac's trackpad

As the title says. I’m unable to navigate the menus (especially scrolling them up and down) with my trackpad. I can, however, select an option by clicking on it.

I’m on an iMac (iMac20,2) with a 3,8 GHz 8-Core Intel Core i7, an AMD Radeon Pro 5700 XT 16 GB GPU and macOS Big Sur 11.0.1 installed.

Is anyone able to help?

Happy new year!

Just checking if anyone is able to help two months after the publication of this thread.
