2 cams, one a pi cam and the second a url OpenMiko webcam

Camera model
Wyzecam v2 with OpenMiko firmware
Official Raspberry Pi cam connected via flat ribbon

What is the problem?
I have succeeded in getting the wyzecam working with OpenMiko and th url
I do want to utilise a second cam that is a official Pi cam connected to the pi board via a flat ribbon (standard connection).
I have seen the Multicam plugin and that seems to be the way forward. However, instructions I have seen seem to be for cams connected via USB. How do I tailor this for one webcam using a url
and one connected to the ribbon connector?

What did you already try to solve it?
I am yet to try this but am prepping for an attempt this week so would like the info before I try (rather than thrash around, not knowing what I am doing)
