Call v120 → current #3Dispatches a call with a specified origin (root only).
View calls on chainCall Workflow
This diagram shows the call execution flow: starting with dispatch_as, passing through validation
(signature, nonce, mortality, fee payment), then pre-dispatch checks, followed by dispatch which emits events: DispatchedAs, and finally post-dispatch where ExtrinsicSuccess is emitted and fees are settled.

// HEADS UP: 2 args below have a complex type with no usable default.
// Look for `undefined as any` and replace them with real values
