After installing the program and saved , it appeared in the dependency but no activity is added.
I would love to see some tutorial to use the imports(via code) without supported activity. Or if this is a bug, any solution?
https://activities.uipath.com/docs/creating-a-custom-activity ,found it so you will need to create a activity yourself and upload via NuGet to uipath . Any easier method please be sure to share with me
