Clipboard for teamviewer window isn't working

Heya,

Downloaded "Other" x86 Teamviewer 15 on Manjaro 20.1.

I cannot copy/paste anything into the Teamviewer client window. Please note, I am not talking about clipboard between client and host. I literally cannot copy paste an ID or my long password into this Teamviewer window while I am able to do so with eveything else on my computer.

Any idea how to go about it?

Thank you,
