UITextField with isSecureTextEntry in Catalyst display an empty box

Hi,

In a Mac Catalyst app, I need to allow the user insert a passcode using a UITextField.

The field is used to insert a one time passcode and I want to keep the content hidden. For this reason I set the isSecureTextEntry property to true.

passcodeTextField.isSecureTextEntry = true

By doing this, a button to allow the user to pick a password from the keychain is displayed:

This option in my case should not appear because the password is a one time password that change every time. For that reason I set the textContentType to oneTimeCode.

passcodeTextField.textContentType = .oneTimeCode

This actually removes the password button, but introduce something weird. If the user type something and then delete everything, a big empty box appear under the field:

I have no idea what this box is and why it appears.

Does anyone know why it appears and how I can remove it?

Thank you
