I have been using AnySoft, but its so buggy at this point, its effectively unusable. Judging by the github, its been in this state for at least a year now. I tried to downgrade to an older version in the hopes of fixing it, but couldn’t get it to install. Is there any better options?
Keychron k6, and a separate phone stand. That is a full size (60%) mechanical keyboard connected with bluetooth. I have and use others (see the other replies) when I need max portability and a quick comment. However a real keyboard beats anything you can do on a touchscreen. I recommend you get one.
