Action only via relationship not work with dependent field

[258034-DuongVietHoang]

I have Event and Attendee resources which have many to many relationship.

I have an action of Attendee that need to only show up on Event resource detail page.

class Attendee extends Resource
{
public function actions(NovaRequest $request): array
    {
        return [
            (new SendMailByTemplate)->showInline()->canSee(function (NovaRequest $request) {
                return $request->viaRelationship();
            }),
        ];
    }
}

class SendMailByTemplate extends Action
{
    public function fields(NovaRequest $request)
    {
        return [
            Select::make(__('Template'), 'template')
                ->options(...),

            Text::make(__('Subject'), 'subject')
                ->dependsOn(
                    ['template'],
                    function (Text $field, NovaRequest $request, FormData $formData) use ($mailTemplates) {
                        if ($formData->template){
                            // set value
                        }
                    }
                ),
        ];
    }
}

This is work fine until I change the select option of the template field which it will call an "action API" which not pass params like viaResource, viaResourceId, viaRelationship which make the canSee return false everytime.

I have temporarily fixed it by change the canSee condition but I don't know if that a right way.

(new SendMailByTemplate)->showInline()->canSee(function (NovaRequest $request) {
                return $request->viaRelationship() || !empty($request->resources);
            }),

Can you explain the requirement you used for canSee() and some screenshot to explain the issue better?

The requirement here is to send email according to the template to the attendees for each event. So the action of sending email according to the template should only appear on the event detail screen, not the attendees screen.
so I set this action to only appear when there is a relationship.

1. I go to the event detail page which list all attendees join that event.
   

2. I select some users and then select the action to send email according to the template.
   

3. I choose email template. Based on the template type I will get data in DB and fill in input Subject and Content. This is also when error happen.
   

When I select template it will call the action API based on the number of dependent fields I have. And importantly it doesn't pass the other parameters viaResource, viaResourceId, viaRelationship so it causes a 404 error at canSee

Yes it doesn't provide those information because it was not designed to be use in such way.
