This needs to be added to upstream first in notify-rust

Since you guys use notify-rust, Look at this:

https://github.com/hoodie/notify-rust/blob/main/examples/schedule.rs

And if you guys are going to upgrade it, please also add actions: support (https://github.com/hoodie/notify-rust/blob/main/examples/actions.rs)
