View calls on chainCall Workflow
This diagram shows the call execution flow: starting with cancel_retry, passing through validation
(signature, nonce, mortality, fee payment), then pre-dispatch checks, followed by dispatch which emits events: RetryCancelled and modifies storage: Retries, and finally post-dispatch where ExtrinsicSuccess is emitted and fees are settled.

Code Examples
// ----------------------------------------------------------------------
// HEADS UP: 1 arg below has a complex type with no usable default.
// Look for `undefined as any` and replace it with real value
// before running — the snippet compiles, but will fail at runtime as-is.
