Option to disable autochange country when typing

[Styort]

I have set up a list of supported countries in the CountrySelectorNavigator (by passing a List<IsoCode> to countries parameter of CountrySelectorNavigator constructor ) and want to be able to enter a phone number for supported countries only. But if I start entering the phone number prefix of another country that I do not have in the list, it automatically changes to it.
Here is a video with an example of reproducing the bug.

Is is possible to disable now?

What would be the expected behavior ?

What would it display when you do +1 ?

Just continue displaying +1, without switching countries.

What do you think about this :

• change the country
• when the user uses a country that is not in the list of selected countries, show an error message ?

I would not like to give the opportunity to change the country if it is not on the list of available ones.

I would like to be able to strictly limit the input of unsupported numbers so that the user immediately understands that the application is not available in his country.

I thought that's what the list of countries in CountrySelectorNavigator was for...
