Views default argument for referencing current user groups

Patch from #8 fixed the issue on Drupal core 9.5.10 and group 2.1.0.

Drupal core 10.2.2 and group 2.2.2
#8 patch works

I used view on search api group index:
add Contextual filters by group id
click "Provide default value" and select type "Group IDs for logged in user"
and "Allow multiple values" to be true

also if it is required you can select Skip item access checks settings in views query options.

Just to note in case someone wants to move this forward: The user permission considered here for bypassing the group access ”bypass group access” has been removed from Group 2 in #3259076: Get rid of the bypass permission → .
