I've created a teams chatbot and have published and installed it as a teams app. I've noticed that upon installation, the chatbot sends automatically a greeting to the user. Is it possible to install the app silently by suppressing this greeting? I am planning to use this chatbot to proactivly send adaptive cards with information and training to selected users as part of a M365 implementation (in addition to answering simple questions), and I would like the first greeting to be the first adaptive card.
If not possible, can I choose which topic that will be the first one, so I can customize it with a one time explanation about the purpose of this bot? If I customize the text that comes now, this information will come very time someone say hello to the bot...
