Edge browser addon-tree-output

Hi I hav a question. can any one help me out??

let me just know how to get source code from Edge browser. I need to debug source from Edge browser but there is no addon-tree-output folder. so I cannot find the source from developer tool on Edge. anyone knows??

I’ve tested with simple host and addons. There is an addon-tree-output with source code with simple addon and host on Edge browser.

this problem is from our app I think. sorry about this post. I think that our app is so bigger to load addon-tree-output on Edge.
