How Will Extensions Update On Chromium based Edge?

How will extensions for this browser update? The process not listed in any documents on the insider website and there are no posts in the forums discussing the topic that I have been able to find. For UWP Edge (what I'm calling Edge that ships with Windows OS), since the extensions are through the store app, they're updated there. But, although Chomium Edge (Insider x64 Edge) uses the same extensions (not counting google store here), they aren't updated through the store app because they're downloaded through the browser. So I would like to know how updates will function to extensions for this browser moving forward.

An example is my Last Pass extension on UWP Edge just received an update to version 4.27.0 through the store. However, the Last Pass extension on Chromium Edge is still on 4.26.0 even though they should be the same extension. I'm not sure how to check for any update, since there's no button anywhere and no documentation telling me that it would otherwise be automatic.

An interesting sidenote (not necessarily related but may be nice to know for any extension devs who wander across this post) is that under the about section for the LastPass extension on UWP Edge the first line says "LastPass Edge Toolbar", but on Chromium Edge the wording is "LastPass Chrome Toolbar". Odd since it was downloaded through the official Edge store, could just be something in their code that looks for Chromium and then changes the wording appropriately. If I look on the Google Chrome Extension Store for the Chrome extension (which I haven't installed on this browser) it's on version 4.27.1. So even if the extension thinks it's running on Chrome it hasn't automatically updated itself to the chrome version.
