I downloaded that plugin to link our telegram group for minecraft to our server.
But I disabled the possibility to forward telegram messages to the server, I just wanted to know when people were dying & connecting. The bot was SPAMMING the message "Sorry, please link your account with */linktelegram ingame* to use the chat!" and all messages were creating a lot of notification.
I had to develop 2 fixes :
* one to remove the message as , I tried A LOT of different configuration and that "Sorry, please link ..." message was spamming everyone.
* one to send ONLY silent messages by adding the parameter to the plugin. See the following telegram doc :
https://core.telegram.org/bots/api#sendmessage (see disable_notification parameter)
I did a local fork in order to have the plugin work as I expect. After those fix, nothing specific to raise (for now ;)
