Make button visible to only 3 specific users

[ACPBSCi]

I'm going batty. I have found many posts and blogs on how to do it and no one tells you the same thing twice. I cannot for the life of me figure out how to hide 1 button from everyone except 3 specific people. It's a button that goes to a new screen and we want to test the feedback survey on that screen. If you are a tester, you will see the button at the bottom of the landing page and no one else. I have tried:

• Hardcoding the tester on the button
• Setting the tester as a variable and using the variable
• Looking up a SharePoint list of testers (list is called "Testers", the Title field is the username the Email column is a people picker showing the work email)

I am doing all of this on the OnStart of the app:

Set(
VarUser,
User()
);
Set(
varUserEmail,
User().Email
);
Collect(
SPTesterList,
Testers
);
Set(
varTesterEmail,
varUserEmail = "first.last@company.com"

);

I am not creating a record. I'm doing all of that, but I can't find the right expression to do something with it. Either the button is hidden at all times or it's visible at all times. What am I doing wrong?

What doesn't work:

• Collect(SPTesterList, Testers); Set(currentUser,User()) ; Set(varTesterEmail,LookUp(SPTesterList,Email=currentUser.Email))
• Set(varTesterEmail, varUserEmail = "first.last@company.com");
• If(User().Email = "first.last@company.com" || "first.last@company.com", true,false)
• If(User().Email = "first.last@company.com", true,false)

Any suggestions would be welcome.

Visible property of button:

User(). Email = joe@contoso.com||

Mary@microsoft.com || bill@usa.gov

User() is a global function that is always available so you dont need to save it to a variable and do anything fancy with it. Just set the visibility to User().Email = firstemail or User().Email = secondemail or User().Email = thirdemail

Didn't see you had literally said the exact same thing before me lol I started to answer then had a work call and came back to finish after. Guess I should start refreshing before I answer when I have to walk away for a bit. 😅

This doesn't work. I get an error that says incompatible types. You have to put quotes around the email address.

"first.last@company.com". I wish this was more intuitive. It worked, though. Thank you. I swear I tried this. I knew it was simple.
