Dropbox on Bazzite

Apparently Dropbox is not straight forward to run on Bazzite Linux, but this worked:

Install Dropbox's flatpak (using Bazaar or other method) but DONT OPEN IT YET!

Then you have to use Flatseal to adjust a few configs:

1 - Add /var/home/{username}to the allowed directories under ‘Other Files’

2 - Under ‘Environment, variables’ add: HOME=/var/home/{username}

(Replacing {username}with your actual user name)
