Mention a member when sending a comment to a thread using API

I would like to mention a member when sending a comment to a thread using API.

Hi, @ReiAkimoto :waving_hand: One place to check out is the Conversations inbox and messages APIs (BETA). Are you saying that you want a feature that is not listed there? Or is there another use case that is documented you need help with?

Best,

Jaycee

Thank you for the message.
Yes, the method I want to use is not on that page, and when I contacted HubSpot support, they told me it’s currently not possible. I hope for a feature addition.
