Dial a phone number in field

[sfilemaker2023]

I would like to create a button next to my phone field so that when it is tapped, the number gets dialled (in FileMaker Go). 
 

anyone know how to do this? Thanks.

A script with the Dial Phone script step?

Hi yes I did try to set it up but it didn't work- but when I change the field format form text to number and back again, the script then worked. 

Thanks.
