If the server version is 1.21.6 or higher, AuthMeReloaded 6.0.0 or newer is installed, and either settings.registration.dialog.postJoin.enable or settings.registration.dialog.preJoin.enable in the AuthMe configuration is enabled, the native AuthMe dialog will be displayed instead of this plugin's dialog.

Available for players joining via Geyser

If the server version is 1.21.6 or higher, AuthMeReloaded 6.0.0 or newer is in use, and settings.registration.dialog.preJoin.enable is enabled in the AuthMe configuration, Geyser will automatically convert the AuthMe pre-join registration dialog into a Bedrock Edition form.
