If you are one that often has way too many tabs on in your Chrome browser, Tab Groups could be a feature you are waiting for. It’s been a while since it’s first introduced but it still remain as an experiment feature that you can enable to start experiencing it.
Enabling Tab Groups in Google Chrome
Open Google Chrome browser, and click the line below to open the Tab Groups section in Chrome’s experiments page.
And select Enabled from the drop-down list and restart the browser.

Enabling Tab Groups in Microsoft Edge Chromium
Open Microsoft Edge Chromium, and click the line below to open the Tab Groups section in Edge’s experiments page.
Select Enable from the list and restart the browser.

How to use Tab Groups feature
Right-click a tab that you want to group, and choose Add to new Group, or Add to existing group if any.

Once you have groups set up, you can give it a name, assign a color to distinguish from other groups, ungroup them, or move entire group of tabs to a new window.

Since Microsoft Edge Chromium shares the same Chrome build, the feature appears the same as in Chrome.
The feature seems to be still in a work-in-progress state where the bugs is being worked out and the new features are being added. One that I am hoping to have is that once I close the entire group, I should be able to open them all back very easily.
