Is there a way to add a feature which had been available on Samsung and Xiaomi devices.

Let’s say i want to call my friend John.

John is subscribed to call waiting.

John is already is on an active call with his wife.

When i had my note 10, and when i call John, john’s line will ring since he had call waiting enabled, the Samsung will show me a toast notification saying “call is waiting”, like the attached photo.

Also in some other phones, there will be an extra beep when i call john and if john is on active call while my call comes in.

I’m currently using a pixel fold and i miss this feature.

Is there a way to add this to this dialer please

I tried to search about this and what i came close to that it’s some feature that is enabled by some manufacturers and not others
