I'm trying to use the GUI in Ubuntu and I have made sure the latest sf cli version is installed and the sfdmu is installed as a plugin. Here's the export from my sf plugins command:

sfdmu 4.38.0

Uninstalled JIT Plugins:
code-analyzer 5.0.0-beta.3
community 3.3.18
custom-metadata 3.3.48
dev 2.5.1
devops-center 1.2.27
signups 2.6.19
@salesforce/sfdx-plugin-lwc-test 1.2.1
@salesforce/sfdx-scanner 4.11.0

The GUI starts just fine but when I try to select the 'Connections', in the dropdown everything is greyed out. I'm guessing there must be some permission issue but not sure what. Can you please help me understand what I need to change to enable the options?
Actually, I remember that the first time I opened the app the first option was available. I clicked on it and got some error (forgot to capture it) and right after, it was greyed out and no uninstalling it reinstalling it got me back to where I could see that as an option.

Thank you!
