Steps into the next asynchronous continuation.
This is equivalent to CDP Debugger.stepInto({ breakOnAsyncCall: true }).
If the current execution schedules an async continuation (e.g. via await,
Promise resolution, or microtasks), the debugger will pause when that
continuation is invoked.
Steps out of the current function.
Continues execution until the current function returns, then pauses at the caller frame.
Steps over the current line.
Executes the current statement completely and pauses at the next statement in the same frame.
If the line contains function calls, they are executed without pausing inside them.
Steps into the next function call.
If the current line contains a function invocation, execution will pause at the first statement inside that function.
