I have two Chromium-based browsers installed on my system: Chromium and Brave. However, both are installed as flatpaks. I'm guessing this is why, when I try to log in to my Slack workgroup from the command line, I get the following error message:

ERROR 004 (Authentication Error): auth error: auth error: no
                      │   browsers found.

Is there a way to get slackdump to recognize/use flatpak browsers?
