In Dynamics 365 classic I was able to use a web resource added to a form to overwrite the click to call handlers and use a custom function:
Mscrm.ReadFormUtilities.openPhoneClient = newCallHl;
Mscrm.ReadFormUtilities.handlePhoneNumberClick = newCallHl;
However trying this in the customer service hub (Unified Client Interface) I get the error Cannot set property 'openPhoneClient' of undefined. Could you please Guide me how can I fulfill my purpose in UCI ?
I have seen it is a known issue but not able to get any solution yet. would be great help if someone can gave me a solution.
Thanks
