User Onboarding process with workflow-core, human steps and events

[GKotfis]

I'm searching for a solution to design and manage user onboarding process in our product.
There are many stages (Signup, KYB processes, AML etc) that can take minutes or days. Mostly it's a human-driven process. We wait for some documents, forms fulfillment or events (async checks). I wonder if workflow-core can help with such a process?
