Haven’t seen this yet, but should be pretty straight forward!
How exactly would you see the process?
e.g.:
Send a slack about X → creates reminder for X in Y days→ reminds you via slack after Y days
Hmm not from the platform directly. But you could hook it up with slack/gmail etc and activate notification sounds on there.
💡 Or you could use a phone calling agent to actually call your friend and remind her about these things
