I have a bot built using ms bot v3 nodejs sdk. I add this bot in my MS team by using deep link for 1:1 conversation which looks like as follows
https://teams.microsoft.com/l/chat/0/0?users=28:{BotID}
I would like to add @mentioning users capability to this bot and I was trying to see if I can get some examples on how to it ?
Not sure if side loading bot as an app will allow it.
Bots and users can only at-mention members of the same conversation.
Right now neither bots nor users can at-mention arbitrary users who are not members of the conversation.
Your example above, "Hello @PersonB and @PersonC please take care of this ticket", can work if PersonB and PersonC are part of the team (if this in channel), or the group chat, but not in a 1:1 chat with the bot.
The deeplink in your question creates a 1:1 chat w/ the bot, so no other users could be at-mentioned :(
