Using arcade.run command to conditionally activate certain app components

Hello and Happy New Year!

I am wondering - since I can't find any examples of using arcade.run (which, why are there like no documented examples of utilizing this operation in a command chain when it could be potentially so powerful?) - does anyone know how I could use this operation in a command chain to check the number of features returned by tasks.identify and based on that number, open one results component or another?

I assume it's something along the lines of:

[
    {
        "name": “tasks.identify”,
        “arguments”: {
            “maps”: []
            “sources”: [<model_uris_for_layers>]
        },
    {
        “name”: “arcade.run”,
        “arguments”: {
            “executeScript”: “IIF(<logic here to check for task.identify feature count and set the component to activate)”
        }
    }
]

For passing results from tasks.identify into arcade.run, should I be referencing $context inside the “executeScript” argument? From what I saw using a context passed into a workflow, context is not simply a feature set and I had to dig in a bit to get the features. Is the context here identical to what I see when looking at the context object (via browser dev tools) passed into VSWF?

Also, how would I pass a ui.activate command out of arcade.run or is this actually not possible and I should instead use a workflow?
