Telegram notification about 17TRACK parcels

Hi there,
I’m trying to prepare sending notification through Telegram about packages that will get status “ready to be picked up” from 17TRACK integration.

For test purposes I have it configured to send notification once some device is turned on. I want to attach to Telegram message information about packages that will be ready to be picked up.

This is my actions section:

and I wonder how should I fill it in to send information what packages are going to be delivered that day.

On Lovelace summary card I use i.a.: states.sensor.seventeentrack_packages_in_transit.attributes.packages and I’d like to try e.g. if there’s similar for ready_to_be_picked_up, but I have no idea how I should send this data.
