load user, his teams, assigned users with role name

[VictoriaNici]

Why this statement not loading user roles for user teams,
at Services/Users/GetUserProfile.php:
$this->user->load(['groups.users.roles']);
I am getting groups(teams), assigned users(belongsToMany relation) but without their roles. Trying different workarounds, nothing works.
also I have this in User model. How can I properly integrate the roleName method within the load statement to retrieve user roles?
at Models/User.php:

public function roleName(string $teamId, string $scope): ?string
    {
        $actualTeamUuid = getPermissionsTeamId();
        setPermissionsTeamId($teamId);
        $role = $this->roles->where(UserRole::COL_SCOPE, $scope)->first();

        setPermissionsTeamId($actualTeamUuid);

        return $role ? $role->name : null;
    }

It works in foreaches, but how get the roles in load (it also not works, how much I tried).
I want to mention that I applied some custom solutions (use uuids).
Thank you in advance for your help.

You could make your own custom query
