Controlling ipad camera live video zoom/rotate/colour etc. e.g. for zoom or teams

Mac has a great 3rd party utility app iGlasses where I can zoom/trim/rotate/colour/saturation/contrast etc. adjust the live built-in or external camera feed that gets sent to e.g. zoom or teams.

I cannot find an iOS built in solution for this, or a third party app that acts as a 'vitrual cam'.

E.g. built in cam -> virtual cam with adjustments -> zoom/teams

Any help on that please?

thanks
