Maybe this helps (never tried):
However, let me just point out one thing. Perhaps you are new to Qubes OS and have been using Ubuntu before and are used to it. If that’s the case, I’d suggest you start out with the debian template. It’s pretty similar and you won’t have any frustrations as everyhting is well integrated by default.
A lot of people come into Qubes thinking they’re going to run their favourite linux distrubutin or even windows without an issue. That’s generally not the way to go. One should start with the default templates (debian-10 and fedora-33) and then move from there. Just a tip 
(not sure if this is your case).
