Workflow and state machine concepts mapping. How?

So if we map to temporal way of coding it then does it mean 1 state machine is 1 workflow or 1 state machine is equal to many workflow?

You can convert a single state machine to a single workflow type or break it into multiple workflow types if it is too complex to be managed by a single team.

At a time we have 100s of similar state machine running.

Each workflow type can have a practically unlimited number of instances (we tested to hundreds of millions) running in parallel.

And these workflows need to be dynamically created and registered which I am not sure if it’s possible or not.

What is the use case for their dynamic creation? Could you just implement them in code?
