Run function 30 minutes from now (delayed function)

How can I get a function to run 30 minutes after an event, say, to send additional emails in reaction to a user sign up.
Scheduled functions apparently only allow for recurring functions (daily, weekly, every tuesday etc etc), but I want a delayed function.

I don't think there is any feature as a delayed function,

But maybe you can create a function thats something like this

        time.sleep(1)
        current_time = datetime.now()```

But then, the max execution time of a function in appwrite is 15mins

It won't work for a 30 mins delay🤔

Delayed functions, hmm, interesting

for something like scheduled functions, you would do something like this https://medium.com/@ujjwal26599/leveraging-power-of-appwrite-to-build-scheduling-applications-40615fa7e7f7

But since you do not want that, maybe you can use counters that are silently triggered upon your event and linked with it.
