I have some custom Forms elements that resides in a shared project. This shared project holds all the episerver code and nuget packages for EPi. The view is with the built in views as indicated in Forms.config (formElementViewsFolder="~/Views/Shared/ElementBlocks"). I have a separet project for EPi Admin and another project for the front end. This custom element doesn't show anywhere with EPi Admin or the frontend project. I would expect it show show under "BasicElements" so I can add it to the Forms block.

I have validated that on project start, it is hitting the StateElementBlock with a breakpoint on weAreHere.
