Running app flow on condition

Hi!
How do I run a flow when a condition is true?

So, from a server connect I receive data about competitions.
Each competition has an end datetime, on server side it moves all to “finished” when end datetime is passed, but to see that the server connect needs to be refreshed.

That’s why I would like to have a flow that (re)loads the server connect when the current time passes the end datetime on the client side.
