I just learned that Telegram was not able to call our webhook after we changed our domain some time ago.
It would be very convenient if the plugin would check the webhook URL at startup and notify administrators about problems. I did not notice any problems, since old users still got their notifications, and new users rarely complain.
[PLUGIN discourse-telegram-notifications] DEPRECATION NOTICE: The file 'discourse/plugins/discourse-telegram-notifications/discourse/templates/connectors/user-custom-preferences/telegram-chat-id-preferences.hbs' uses the deprecated .hbs extension. Refactor it to use '.gjs' instead. [deprecation id: discourse.hbs-extension] [info: https://meta.discourse.org/t/398896]
I also noticed there are quite a few open pull requests in the repository, so I was wondering whether the plugin is still actively maintained.
