It is not a product package, hence it is Wx, and not Wm. It was developed by developer enthusiasts This requires consulting services engagement. If your org do have consulting sales or consulting services engagement, you can talk to them to get the license of this package ( custom license, not product license that you get through sales team ).
You cannot raise any queries on Wx package with Global support team as GS supports Product packages and works closely with RnD for issue resolutions on Wm packages, not for any Wx.
