What linux distro are you using? That might help to get to the bottom of this
I learned with my computers (all running CachyOS, a derivative of ArchLinux), there actually wasn't a dialout group -- instead, it was tied to the group 'uucp' - once I added my user to that group, I had no issues with the Tangara Companion flatpak or CLI.
It might help to verify what group is assigned permissions to '/dev/ttyACM0'. You can try one or both of these:
-- In the terminal, run the command "ls-l /dev/ttyACM0"
You should see something like this as an output -
❯ ls -l /dev/ttyACM0
crw-rw---- 166,0 root 31 Jan 02:02 /dev/ttyACM0
In my case, it didn't show me the group (you should see something like 'root dialout'), so I got creative
-- In your file manager, go to "/dev", and find the object "ttyACM0"
Right click on this object and choose Properties
Look at the permissions - this should tell you what group has access to the device.
Then assign your user to the group assigned, and don't forget to log out and back in afterwards. Hopefully that helps!
