Teams Apps (MS apps) use First Name instead of Display Name

However it's not the Display Name that needs to be edited. We have changed the Display Name to be what the user wants, but sometimes apps in Teams decide to use the First Name value instead of the Display Name value. The First Name value is their birth name since First Name is established by our HR system. But if they don't identify as that first name anymore, they'd rather it not be used. So, I'm just seeing if I can do anything at all to help - like ask Microsoft if there is some magical way of requesting Microsoft apps to use Display Name instead of First Name.
