Logging in as an external user on Ideation Portal does not allow access to idea group if "Manage External Users" is disabled.

Issue Summary

When an external user logs into the Jira Align Ideation Portal as a member of a public group, if "Manage External Users" option in group is disabled, user will be presented a "You don’t have access to this idea group. Please login or register." error.

This is reproducible on Data Center: yes

Steps to Reproduce

1. Create an ideation group that is public but does not have "Manage External Users" enabled.
2. Register an external user using the external link generated by the group.
3. Log in with the user once created.

Expected Results

User can log into the group and view ideas/vote without approval. This was the behavior in prior versions and known working in 10.109.3

Actual Results

User receives "You don’t have access to this idea group. Please login or register."

Workaround

Workaround is available by enabling "Manage External Users" as once enabled, external users will work as expected. However this requires active management of users once enabled.
