Hi,
I have created a powerapps forms to be used in a sharepoint list. I want a certain field(Assigned to) to be visible to only specific people (to be exact, one absolute mail which is mine & one mail id which will be assigned over in the form). Attached the powerapps image below.

I used a formula in the visible field as in the below image(blacked out is my mail id).

It is showing up in Powerapps forms. But not showing up in my sharepoint list

Could someone please help?
Thanks in advance!!!
