Hi Jaymer,
The previously shared oml (demo implementation) is the same demo application linked with the FullCaledar2 Forge Asset. If you are referring to dependent modules as other services? Then you can download the complete bundle from the forge asset screen.
Note that the FullCalendar div export to image implementation is driven by the referenced third-party JS library Html2Canvas and along with a bit of custom JS to download the image.

Still, if you face challenges in implementation, we can help if you share your oml file with the implementation.
I hope this helps you!
Kind regards,
Benjith Sam
