How to add module in MobileLeadRecordPageSettingsDefaultWorkplace

Hello Guys,

 

I have to add a UsrCustomLeadEditPageController module in MobileLeadRecordPageSettingsDefaultWorkplace.

To do this I was trying to create a replacing view model but it was not listing MobileLeadRecordPageSettingsDefaultWorkplace in Parent object.

Please help me to know, how to create model in custom package to add controller module.
