There can be controlling on callback function and if you want use to data-attributes.
Moreover, add/remove class at right timings.

Optional (demo) case

Callback mthods to Proxemics 3rd param.

Proxemics('.prox', {
    territory: 100,
    debuggable: true
}, (_, Styles) => {
    if(_.el.classList.contains('one')) {
        Styles({
            filter: `hue-rotate(${_.angle}deg) saturate(${1 - _.distance * .005})`
        })
    }

    if(_.el.classList.contains('two')) {
        Styles({
            boxShadow: `inset 0 0 0 3px hsla(200, 100%, 40%, ${1 - _.distance * .005}`
        })
    }

    if(_.el.classList.contains('three')) {
        Styles({
            transform: `rotate(${_.angle}deg)`
        })
    }

    if(_.el.classList.contains('four')) {
        let speed = Math.min((_.distance / 500) + .2, 1).toFixed(1) // from .2 to 1
        Proxemics.SpeedTune = () => _.el.style.setProperty('--speed', `${speed}s`)
        _.el.style.color = `black`
        _.el.addEventListener('animationiteration', Proxemics.SpeedTune)
        _.el.innerHTML = speed
    }
