openSettings method
Bot API 7.2+ A method that opens the biometric access settings for bots. Useful when you need to request biometrics access to users who haven't granted it yet.
Note that this method can be called only in response to user interaction with the Mini App interface (e.g. a click inside the Mini App or on the main button)
Implementation
BiometricManager openSettings() {
_bm.openSettings();
return this;
}
