createChannelBan

Permanently bans a member from a channel. Moderators can't add banned members to a channel. To undo a ban, you first have to DeleteChannelBan, and then CreateChannelMembership. Bans are cleaned up when you delete users or channels.

If you ban a user who is already part of a channel, that user is automatically kicked from the channel.

The x-amz-chime-bearer request header is mandatory. Use the ARN of the AppInstanceUser or AppInstanceBot that makes the API call as the value in the header.
