Why does the vk bot only respond to notifications in a conversation?

Question

In contact with

I made a bot in C#, added it to the conversation, and it only answers if:
1) At the beginning of the message there is a slash - '/'
2) I contacted the bot via @ or *
In the first case, it will return "/message"
In the second case, it will return "[ public123123|@public12123] message "
Is there a checkmark, setting, or what else in VK so that it responds to all incoming messages?
Many other bots respond to all messages, there are even questions on how to combat this, but I have the opposite problem

Answer 1

It seems like the conversation admin gives permission to all messages.

Answer 2

Yes, it can only be given by the admin of the conversation

Answer 3

Having registered the code, in the chat itself you need to give permission to the ADMIN, so that he gives the right to messages to the Bot. That is, the participant assigned him a "name".

Answer 4

You need to give access to all messages in the chat itself and you can do this from a PC

Answer 5

You need to give the bot an admin panel in a conversation and access to correspondence
