How to get update information of Microsoft Edge Extensions

Question

I can download every Microsoft Edge Add-On (Web extension) as a .crx file by using this URL:

https://edge.microsoft.com/extensionwebstorebase/v1/crx?response=redirect&x=id%3D[EXTENSION_ID]%26installsource%3Dondemand%26uc

[EXTENSION_ID] is the ID like "elhekieabhbkpmcefcoobjddigjcaadp" for this Add-on.

I use this for using in a WebView2 control.

But before downloading an update, I would like to check, if an update of the Add-on is available.

How can I get version information of available Edge Add-ons?

Currently there is no API to obtain Edge extension version information, you can refer to this document: https://learn.microsoft.com/en-us/microsoft-edge/extensions-chromium/developer-guide/api-support.
