findGroupByName

Finds and retrieves a group by its name.

This method searches for a group identified by the given groupName. If a group with the specified name exists, it returns the corresponding Group object. If no such group is found or if the groupName is null or empty, the method returns null.

This method is useful when you need to retrieve a specific group's details based on its name without performing an operation that requires asynchronous processing.
