Hello,
Think I may have found the solution.
I believe what you were searching for “1de348d0-a422-11eb-93b2-02422a41f7ab” is the permalink for the message.
Example as shown below.
Also I found this
EDIT:
If your using GL4 try something like this.
Insead of using gl2_message_id use _id: 1de348d0-a422-11eb-93b2-02422a41f7ab and search for ALL message see if you find it.
Example:
I tried it on a couple messages and it worked for me.
Hope that helps.
