When connecting to a BC sass environment we need to be able to pick from a list of many M365 (o365) accounts for authentication to the new connection

Many sites, including this https://experience.dynamics.com/ideas site.

When connecting and starting a new session, the user is promoted to pick from multiple O365 logins that are present, and authenticated (cookies?) in the browser

At very least, when requesting to "Sign out" a pick list to select the appropriate account(s) to sign out of so that the one that remains will be used for the next log-in would be most helpful and not force us to use an uly combination of clearing cookies and private or "incognito" mode browser tabs.
