While testing, it seems I discovered a bug in the plugin. After I send a message to the chat via Telegram → Discourse, nothing appears on the site in the chat (sometimes only 1234567890.tgid username appears). To solve this problem I have to refresh the site page. After updating, the name of the message sender appears, but the contents of the message itself are not shown. To solve this problem, I rearrange the HTML and then the chat message text appears. Here’s a video:
Also, I wanted to clarify. If I send a message via Telegram to a group chat without using the Reply button, the message does not reach the chat in Discourse. It turns out that in order for the message to be sent, I must select the Reply function in telegram chat. But what if I don’t want to respond to anyone’s message in the chat, but just want to send a message with a question to all group members?
