I'm trying to set up a simple issue tracker using the template in Microsoft Lists.
Items in Microsoft Lists now have the ability to have an associated conversation, as shown in the screenshot.

What I'd like is:
- a dedicated Issue channel in a Microsoft Teams (done)
- a flow that takes new conversations in the Issue channel and based on the message content, creates a new issue in the list (done)
- for the flow to replace the new issue item's associated conversation with the conversation that was already started in the channel
Part 3 is where I'm struggling. I can't find where the association between the item and its conversation is stored. It doesn't appear to be in a visible column in the backing SharePoint list. Any ideas where I can find this, so I can use it in a flow?
EDIT: I've discovered that you can add the same list to multiple channels and have different conversations for the item in each channel. This means, presumably, that the association is not being stored in the SharePoint list, but is being stored somewhere in the Teams channel - perhaps in a message.
EDIT 2: According to this Microsoft representative, "if you comment on a list item, those comments are stored within the list schema itself; think of it as an additional column of data per row." How, then, can one access that data?
