Microsoft Edge Chromium offers an option in its Settings to clear browsing data when you close it, you can choose what to delete from Browsing history, Download history, Cookies, and other site data, Autofill form data, etc. If you’ve configured Edge to auto-remove cookies when you exit the browser (which signs you out from most of the sites), in each session, you need to input login credentials every time for the websites you regularly visit, to avoid this, latest Edge Canary 83 provides a new option under Cookies and site data in the edge://settings/clearBrowsingDataOnClose page to keep specific cookies.
Prevent Edge from clearing cookies from certain sites when you close Edge browser
1. Launch Edge Canary 83.0.470.0 or later
2. Click on ellipsis icon > Settings > Privacy and Services > Choose what to clear every time you close the browser, click on or select to enable “Cookies and other site data”
3. Click on Add and type the site address one by one for which you don’t want Edge to clear cookies when you close the browser.
Edge’s newly available “Do not clear” option informs the user that “You’ve allowed the following sites to save and read cookies on your device. Cookies for these sites won’t be cleared when you exit the browser”.
From now on, except for sites you’ve whitelisted above, other cookies will be deleted automatically when you close Edge. FYI, Google Chrome doesn’t provide Clear browsing data when you exit option.

It doesn’t keep the Allow list when cleaning the history, even then the clear the cookies checkbox is unchecked.
Also, there is no export tool to export the list of added sites.
That allowed cookie sites list is not impacted when you clear browsing data, we can confirm this in Edge 83 stable.
I am having the same problem. It does not keep the allowed list when I close my browser, the allowed list disappears.
