Chrome in Android, how can I find a tab of links that were removed from my "archives"?

I'm kinda devastated, I'd been keeping a list of places my wife and I have been wanting to eat at across the world. I know a bunch of tabs with Google searches isn't a great way to keep a list, but it was what I was doing.

They were moved into "archived tabs" whenever that became a thing, and now I've just learned there was a change that defaulted archived tabs into being removed after so many days of inactivity.

I don't know when this went into effect, and I don't know how I'd search my history to find a bunch of closed Google searches, but if anyone has any ideas when this change went into effect so I could narrow my search, or any ideas on how to bring back dead groups of tabs, I could really use some assistance. Until then I'm just going to scroll through my history... Which feels so futile.

Edit to add: I had even named the tab group, I searched in the history for the tab group name and was unsuccessful.
