How to send a chat message using BOT

I have an APP with a BOT in Teams, I want to send a request that allows the BOT to send a card to the user. My intention is not to use them as proactive messages, I'm just trying to send them through Microsoft Graph.

I can send a card between users using the method:
To create the CHAT and get the ID: https://graph.microsoft.com/v1.0/chats
To send the CARD to another user: POST /chats/{chat-id}/messages

I want to send a card from a BOT to the user, I tried using the same method as above, I passed the APPID and the user ID to create the chat, however it returns 403, but it doesn't specify the permission:

{
"chatType": "oneOnOne",
"members": [
{
"@odata.type": "#microsoft.graph.aadUserConversationMember",
"roles": [
"owner"
],
"user@odata.bind": "https://graph.microsoft.com/v1.0/users('APPID')"
},
{
"@odata.type": "#microsoft.graph.aadUserConversationMember",
"roles": [
"owner"
],
"user@odata.bind": "https://graph.microsoft.com/v1.0/users('USER-ID')"
}
]
]

Does anyone know how to make the BOT send the CARD to a user on Teams?

    Graph and Bot are two unique ways to send messages to users. Graph at the moment only supports sending message in delegated (on behalf of user), while Bots only can send on their self (effectively application permissions).

    However from the call it looks like you are trying to create a chat between a user and a bot. Refer to https://learn.microsoft.com/en-us/microsoftteams/platform/graph-api/proactive-bots-and-messages/graph-proactive-bots-and-messages on how to create a chat between a user and a bot.

    One the conversation is created (your bot will get a conversation event) refer to https://learn.microsoft.com/en-us/microsoftteams/platform/resources/bot-v3/bot-conversations/bots-conversations
