Recalculate expression for visibility

Hey guys, I want a button to show up not earlier than 30 minutes before a defined Date and Time. Unfortunately, the expression does not seem to be recalculated regularly. So even when passing the 30 minute barrier, the button remains hidden until the page is refreshed. How do I make the button appear ecactly 30 minutes before the defined date and time?   Thanks Jonas

You have to refresh the object to do is. Conditional visiblity is checked on load of the page. Without refresh the object, this will not be rechecked. There is a microflow timer widget which can execute a microflow every specific time (f.e. every minute).

And i don't know the exact requirements for the visibility, but if I was you, i would recheck your statement
