public function assignee() {
return $this->belongsTo(User::class);
}Tables\Columns\TextColumn::make('assignee.initials')public function owner() {
return $this->morphTo('ownerable');
}Tables\Columns\TextColumn::make('owner') will display the owner object and it's ok but Tables\Columns\TextColumn::make('owner.initials') will result in empty cells. Someone can give me some help ?
