During the winter, my phone is located in my snowsuit or jacket pocket rather than my oants pocket. Due to the possibity of misplacing my phone, I set a three minute timer! So my phone will announce itself !
This Shortcut initially deletes any pending alarm named HomeModeFindPhone then creates a new alarm labeled HomeModeFindPhone
Delete HomeModeFindPhone alarm twice, but create only if RepeatIndex=1
Shortcut execution reaches this comment only if a person presses Continue button, from above Action.
