Trigger notification by state contains "Morgen"

"Hello,

I’m very new to the notification section. I have a waste collector integration that shows when the trash bin is collected. Now i want to sent a notification when the state contains “Morgen” (tomorrow).
How do i set this up?
The state varies between, “date” and “day and date”.
Here is an example of the state:image
Hope someone understand it and can explain to me how to set up the notification.
