Speckle ArcGIS pro 3.1.3 toolbox does not appear

I want to export my Arcgis feature layer to speckle to communicate with Rhino using Grasshopper.
After installing the arcgis connector in speckle manager it gives the following error

“Some of the installed connectors do not share the same 2.x version, this could cause issues.”

It doesn’t show the toolbox in ArcGIS. I’ve tried to reinstall the connectors, but nothing has worked so far. What should I do to fix this problem?

Hi @Janneke ! Please install the new ArcGIS connector from speckle-releases
