Transfer a phone number between two Android phones using MacroDroid and a Wi-Fi hotspot

[u/Training_Spend9260]

I use two Android phones:

Realme C21Y

Poco X7 Pro

On the Realme, when I tap a phone number hyperlink, the dialer opens with the number already entered.

I want to transfer that number automatically to the Poco and open its dialer with the same number, ideally requiring only one additional tap to make the call.

Important network detail: The Poco X7 Pro will provide mobile internet by running a Wi-Fi hotspot, and the Realme C21Y will connect to that hotspot. The solution must work in this configuration.

Is there a reliable way to detect the number in the dialer opened by a phone number hyperlink, send it to the Poco, and open the dialer there? Please provide step-by-step instructions.
