Stuck Trying to Update Standard Item Appearance

I'm trying to run this script to update the look of a standard item in a floating menu.

async function getStatus() {
    try {
        const response = await fetch('http://localhost:3491/v1/status', { method: 'GET' });
        const result = await response.json();
        console.log('Got Status:', result);
        return result;
    } catch (error) {
        console.error('Error Getting Status:', error);
        throw error; // or return null, so the caller can tell it failed
    }
}

I'm trying to update the button from one SF symbol to another.

I get to the section below, but I have no idea what to enter to trigger the alternate symbol. HELP!

"You can activate the alternate appearance by either using the predefined action "Update Floating Menu-ITEM Properties" or by setting BTTMenuAlternateModeActive to 1 via script

Or specifc a variable that will activate alternate mode when true"

This is the response I get from my script

{"call":"inactive","control":"system","mute":"active","record":"disabled","share":"disabled","status":200,"teams_api":"disabled","version":"4.11.1","video":"disabled"}

I am not sure I understand, this script is not related to BTT at all. It seems to call a status endpoint from some other app/server?

Sorry - This is the button I'm trying to make work, that code should paste into BTT
