Ionic native call number BypassAppChooser to false not working

I’m trying to make a simple call number function where users have to choose either viber or phone etc to make the call,

i used the @ioni-native/call-number plugin and set the bypassAppChooser to false, it still redirect to the usual dialer to call not prompting to select viber.

I might have set a defaul before but checked it’s not , tried reinstall the app still the same.

can someone help me please, im just a newbie thank you!.
