Group JSON:API Create Access
This project fixes an issue where you couldn't create new group relationships through JSON:API. It adjusts the access checks to properly consider the group specified in the request.
Provides a solution for an issue with the Group module that prevents creating new group relationship entities using JSON:API.
#2872645: Creating `Group` content is impossible via REST, JSON:API and GraphQL due to `$context['group']` being required in checking `create` access
Features
Replaces the _entity_create_access requirement on the JSON:API POST route for group_relationship access, with an alternative requirement that makes the group specified in the request body available as context to the create access check, allowing the group module's access logic to work correctly.
