Can't use Google assistant on my Galaxy buds?

[Samswe]

I've tried everything it feels. Whenever I go to the Galaxy wearables app and choose what to have on my long press only bixby shows up? I didn't get the option to chose a voice assistant when I installed the buds (also reset them) like others have when I Google searched it.

I have a Galaxy S20+ and Galaxy buds +. Anyone know what I'm doing wrong?

I have a galaxy s10, I managed to revoke the "default" option, but not the authorisations, those remained grayed out.
