Date/Time evement triggered at a date

Hello,

I would like an event to appear on a specific date and remain visible for the duration I have dynamically assigned to it.

Thanks

What is an Event? (some ‘thing’ in your database?)

And where do you want it to appear?

yes I want a button to appear in one of my tabs. The user programs on a calendar so that this button appears at a specific time and for a specific duration (this duration is not fixed, it is dynamic)

Of course I have already done everything but I can’t make this button disappear when the display date + duration are exceeded.
