Enable guest access to view resources

[lspgn]

Environment

• Peering Manager version: 1.2.0-dev d4bb98aa27c4

Steps to Reproduce + Observed Behavior

When clicking on any link, if the user is not logged, they will be redirected to the login page.
Tried to disable this feature with:
LOGIN_REQUIRED = False in configuration.py without success.

Expected Behavior

In v1.1.0, the default behavior allowed guest access to the resources. I believe this is preferrable for other teams to be able to easily access the resources without changing them.

It looks like it comes from the permission_required = "peering.view_mymodel" which has been introduced to be able to restrict some views to users. I wonder if it's possible to remove the permission requirement if LOGIN_REQUIRED = False.
