Widget Injection not working in mercurjs2.0

[Eric-Tianwei]

I am trying to inject some custom widget into vendor panel. I tried the medusa instructions which only work of medusa but not mercurjs. I also tried a lot of other ways. None of them works. Does anyone know about it? AI model said mercurjs doesn't support widget injection. If so, is there any ways to enable this feature? Or are there other ways can do same things? I try not to add a new page because I am modifying product related page which is very complex. Thanks for help! 🙏
