Hi there.
If I understood your description correctly, I would say that the scenairo could look as it’s shown in the following screenshot. Note that it is just a draft and it is not personalized for your exact needs, but the logic with the routers and filtering according to post types (text, video, photo) should work in general
If you haven’t done so already, I would suggest navigating to Make’s help section and finding the documentation for each service to get the info about how to create connections to these services.
Hope this helps to set you on the right track.
Cheers,
