Using my Lumix G9 as a webcam

Hi everyone,

I have setup my LUmix G9 as a webcam thanks to this software :

https://www.panasonic.com/global/consumer/lumix/lumix_webcam_software.html

It makes my lumix a great webcam and I would like to use it in Camtasia.

I can see my G9 as a webcam in software like zoom,... but it is not listed in Camtasia.

What kind of setup I have to do in order to make it work?

Thanks

David
