Anyone can help me.

Answer 1

Hello @System Administrator,

Thank you for reaching Microsoft!

You can use Teamwork.Migrate.All Application permission to send channel messages using Graph API.

But the Application permissions are only supported for migration. In the future, Microsoft might require the customers to pay additional fees based on the amount of data imported.

Reference document: https://learn.microsoft.com/en-us/graph/api/chatmessage-post?view=graph-rest-1.0&tabs=http#permissions-for-channel

Hope this helps.
