I want wanted to configure a select widget in my WAB code on my local to have only the selectBy Polygon instead of the out of the box SelectBy square settings. So I created a new WAB app with those settings, downloaded the code, and attempted to copy the new select widget from the downloaded folder. I immediately realized there was no Widget.html file and no manifest.json file. Everything else looked similar in terms of file structure. I also noticed that the Widget.js code looked a lot different (It was no formatted correctly and looked almost minified) than the original select Widget.js file. For example, there was a selectBy parameter in the new code, but nothing in the original code (I thought maybe I could just modify the original). Any suggestions as to what's going on here? The new widget definitely won't add to my app view without those missing files.
