What program (service) can be used to program and test a multi-step process?

Question

Software and Internet Services

There is a process that is simple in essence, but long in terms of the number of steps. I wanted to create a flowchart of this process in some program and be able to test it. Like I clicked on "play", and the first step appeared, you choose the option, the second step appears according to the programmed scenario, you choose the option, the third step and so on. For the program to follow the specified scenario. But so that at the same time this could be done by a user who does not have programming skills and does not have knowledge of languages ​​for describing business processes. There are services in which you can program scripts for the call center. Here's something similar... Preferably either web services or under macOS.
