Hi,
Thanks for the documentation link and the information.
The reason it’s not working is that there is no integration with that hook, but based on the documentation it might be possible.
Can you send me a copy or a download link to that plugin so I can test it?
I can’t promise anything though as this is a 3rd party integration request, however if it’s not too complicated I can definitely make it work for the upcoming version. The documentation looks very promising, but I can’t tell for 100% unless I try it.
