How to show list have mixed rows that can be deleted while some rows that cannot be deleted?

Hope you enjoying WFM. I had a query, we are showing a list of both external and internal users. While internal users are federated and cannot be deleted. Only external users can be deleted. We have two conditions to be fulfilled :

1. Both type of users to be assigned roles. Multi-select users and assign them to the role.

2. Multi-select users and delete them ( only external users )

So since we have two type of behaviors showing them together, I am facing problem if a user selects both types then what to show

It would be really helpful any suggestions to get rid of this roadblock. Be safe
