Hi Venkatesh,
When you are booking your appointment on OnSubmit button call a nanoflow & write the logic.
Logic :- Make a new nanoflow -> inside nanoflow 1 call email microflow from email connector module & send the email then take send message activity inside the nanoflow & pass the number $currentObject/phoneNumber ( I am assuming you have current object which have phone number inside nanoflow) by doing you can get text, email notifications.
If you want to use custom notifications try to use firebase push notifications in native.
I hope you like the answer
Hi Mohammad Saqib, The scenario is that a person can book appointments in the native app and get notified via text, email, or notifications on the other end
