Request permission for biometric authentication

Good afternoon Devs! I'm playing with biometric authentication on Android, but I'm having trouble asking the user to use biometrics authentication, although I have declared in Manifest.xml, I can not make the request via UI so that the user allows and I can call the dialog which will authenticate and in the settings of the app installed on my device shows that it needs this permission. How do I request permission like this for the user? Manifest.xml <uses-permission android:name="android.permission.USE_BIOMETRIC" />

clicking on the button to authenticate I call this method and if it would be the one responsible for verifying the permission and requesting it if necessary:

//iniciando o biometricPrompt
public void authenticationUser(View view){

    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.USE_BIOMETRIC) != PackageManager.PERMISSION_GRANTED){
        //solicitando permissão para o usuário para utilizar a biometria
        ActivityCompat.requestPermissions(BiometricDemoActivity.this, new String[] {Manifest.permission.USE_BIOMETRIC},
                MY_PERMISSIONS_REQUEST_USE_BIOMETRIC);
        return;
    }

    BiometricPrompt mBiometricPrompt = new BiometricPrompt.Builder(this)
            .setTitle("Demo Autenticação por Biometria")
            .setSubtitle("É necessário a autenticação para prosseguir")
            .setDescription("Esse aplicativo usa autenticação por biometria para proteger os seus dados")
            .setNegativeButton("Cancel", this.getMainExecutor(), new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialogInterface, int i) {
                    notifyUser("Autenticção cancelada");
                }
            }).build();

    mBiometricPrompt.authenticate(getCanceledSignal(), getMainExecutor(), getAuthenticationCallback());
}
