Building dual navigation paths in the app (business vs end user)

I’m trying to build an appointment booking app for small businesses - this requires me to build two separate journeys, one for businesses and one for end users but so far all users seem to be treated the same in a single UX.

Can someone point me in the direction of the answer please?

Can you show in a video or some screenshots what you got so far? How are you differentiating the two journeys using the signed-in user’s role?
