GJ integration activity missing check for group access
The checks to determine if a user can see access in GJ is only checking that the group is approved. This means it's possible to see activity for a group a user can't actually access. The data usage needs to be expanded to check for group access as well as view access to the integration. The check in the integrations is intentional and does not need changed, but GJ module also needs fixed for 2.5.3 stable.
