Sub header is not being shown in chat

I am using { "head": { "text": "header", "sub_head": { "text": "sub header" } } }

but the sub header is now being rendered,

The incoming Webhook message show the connection name, as well. How can we turn it off?

Hi @diwakar.prajapati
Thanks for reaching out to us and welcome to our Developer Community, I am happy to help here!
Have you been able to troubleshoot this on your end?

I can still see the Connection in my zoom chat.

Could you please describe more details about this issue?
I do not understand what you mean @diwakar.prajapati

I have the same issue.
Posting json from the docs to Sign In | Zoom

  "head": {
    "text": "I am a header",
    "sub_head": {
      "text": "I am a sub header"
  "body": [
      "type": "message",
      "text": "I am a message with text"

leads to
I am a header

Connection: test

I am a message with text

with the subheader content being replaced by “Connection ” .

I’d post a screenshot of the message, but it’s not allowed.

Is there any update to this question? I still could not see the sub header being rendered in the webhook chat.
