Is there a way to Group a table with morphToMany relationship?

I try create a group table with relationship on role like this :

$table
  ->groups([
      Group::make('roles.name'),
  ])

$table
  ->groups([
      Group::make('roles.name'),
  ])

$table
  ->groups([
      Group::make('roles.name'),
  ])

$table
  ->groups([
      Group::make('roles.name'),
  ])

It return error like this.
