Two different messages when the pro status is ended

when the pro status is ended the user get message that we can set in the pro site configuration.

the same message appear on the backend (wp-admin) and front end if we decide it.

what i want is to write two different messages one for the front end and the other from the backend.

the front end message need to be very clean without any information because every user that enter to the client site will see this message.

so if there is any filter or hook that i can use to create my task?
