Not working with KeepassXC

[rh-sp]

Hello :)

First of all, great job making this available to all desktops!

I am using KeePassXC as a secret service agent and can't get it to work with this version of GOA.

The version that came with Mint 20 sometimes worked, eventually broke; but this doesn't work at all.

How to reproduce:

• Disable / stop everything related to gnome-keyring
• Start KeePassXC, enable Secret Service Integration from the application settings, expose a database from the database settings
• Start Online Accounts, click e.g. Google, then "Sign in..."

Expected behavior:

• Google login page opens in my browser

Actual behavior:

• Button is grayed out, nothing happens

Additional information:
The following is logged in the terminal:

GoaBackend-Message: 00:23:00.594: oauth2_secret_run_task: com.googleusercontent.apps.44438659992-7kgjeitenc16ssihbtdjbgguch7ju55s:/oauth2redirect - 44438659992-7kgjeitenc16ssihbtdjbgguch7ju55s.apps.googleusercontent.com

** (gnome-online-accounts-gtk:34048): WARNING **: 00:23:00.624: Problem adding an account: Failed to connect to session keyring

I don't know if it's actually a problem in KeePassXC's secret service implementation, but other applications work with it (e.g. Slack), they can even start KeePassXC and trigger it to prompt me for my password after some additional configuration.

Hope you can find a solution for this, it would be very useful!
