Inquiry on Controlling Automatically Added Image Comments in Grafana Slack Notifications

I have a question regarding Grafana Slack notifications.
I am effectively using custom templates to configure Slack notification messages.
However, I wish to control the comment-style additional information that is automatically included in the Slack notifications (refer to the screenshot for details).
This information is set up through grafana-image-renderer, and I am looking for ways to customize or remove it. Could you share any advice or possible solutions on this matter?

Additionally, I would also like to inquire if it’s possible to extract and send only the image as a message separately.

Thanks a lot!
