Nested Branching

Does anyone have a good example of how to do nested branching? I am seeing (probably old) info out there that says to create nested workflows, but its not working at all and I spent a good deal of my afternoon on this. My flow is simple and I would think this would be simple too. Agent calls tool that wraps a workflow. First step as an A or B path. If A it needs to run another tool and then it has another A B branch. .branch([ [async ({ inputData }: { inputData: { intent: string } }) => inputData.intent === 'create', fullStep], [async ({ inputData }: { inputData: { intent: string } }) => inputData.intent === 'refine', individualStep], ]); Basically i fullStep to branch again. I may be bleary-eyed from staring at this, but its just not making sense right now.. Thanks!

You can use workflows in the place that you are using step inside the branch. It would be something like: 
const furtherBranchingWorkflow = createWorkflow(...).branch([[() => ..., fullStep],[()=>..., anotherStep]]).commit();

 
originalWorkflow.branch([
        [async ({ inputData }: { inputData: { intent: string } }) => inputData.intent === 'create', furtherBranchingWorkflow],
        [async ({ inputData }: { inputData: { intent: string } }) => inputData.intent === 'refine', individualStep],
    ]);
const furtherBranchingWorkflow = createWorkflow(...).branch([[() => ..., fullStep],[()=>..., anotherStep]]).commit();

 
originalWorkflow.branch([
        [async ({ inputData }: { inputData: { intent: string } }) => inputData.intent === 'create', furtherBranchingWorkflow],
        [async ({ inputData }: { inputData: { intent: string } }) => inputData.intent === 'refine', individualStep],
    ]);
