How do I reduce tabs in Chrome but save the sites for later reference

I lost the tab that explained how to get Vivaldi Session Manager into Google Chrome. Can someone refresh me?

Vivaldi is a browser in it's own right. Vivaldi Session manager is part of Vivaldi Browser and it's built in.

Chrome Session Manager is an addon for Chrome browser:

Session Manager - Chrome Web Store

I've not used Chrome for ages. Maybe this addon can find and restore previous sessions after installation - then again maybe it can't.
