I have a custom header with an image, and when the image is clicked, a Header action was dispatched. How to show the current avatar image in the field? ```php protected function getHeaderActions(): array { return [ Action::make('changeAvatar') ->label('Canvia foto d\'alumne') ->modalWidth('sm') ->form([ SpatieMediaLibraryFileUpload::make('avatar') ->alignCenter() ->label('') ->avatar() ->collection('avatar') ->circleCropper() ->imageEditor() ->acceptedFileTypes([ 'image/png','image/jpg','image/jpeg' ]), ]) ]; } ```
