Entity reference field selection

This is certainly possible. If you browse through the available sample models in the Library, you can find a lot of examples on how to send emails to a list of users. You will need to modify that towards your own selection criteria, though,

Your model would have to start with the event Insert content entity and then you would have to use one or many conditions to verify that all your requirements are met and then you can loop through the user list and send each of them an email.

Really thank you for your replay.
i can see the library and also i do many test with event.
but i cant find any solution when " insert content entity " and the admin user select for example term with name " Apple " after save it should check the selected term and then do something like send email to users grouped by role.

Why i cant send [node:url] when using trigger but when i use normal send email i get the [node:url]
please find the attached attached

The sub-process X1 doesn't know any entity other than the user, which is forwarded to that custom event by Trigger X1. If that custom event should be aware of the node entity from the calling process, then you need to forward that entity as a token as well.

What's the status on this?
