How do I send comment to the planner Task that has been just created. Conversation Thread comes to null for them

Question

I know conversations are on the group level, but https://graph.microsoft.com/v1.0/groups/******-****-4f19-be0e-********/conversations does not give any conversation id of newly created Planner Tasks. I need to send some comments while I create a task or maybe right after it, but with conversation thread coming null I have no option other than manually commenting on the platform. When I create a new task through a service I do get one comment by default stating "New Task has been created" but apparently that comment has no conversation id. Attached is an image of the default comment given to us without any conversation Id. Like I said if I have conversationsid then I can easily post a comment to that id or reply to it.

I am trying to send a comment when I create tasks like other fields such as startedDateTime and descriptions but somehow comment can not be posted from the beginning.

I could not mark your response as an answer but thank you so much it worked the way you said. Basically I created a thread in the group level and Update specific task with that conversation thread Id and now the comment I made to the thread is posted on the task.
