Hello, im working on a reading of overlays interaction from the Rest Api but im not able to get the background-color/Position of it (see the picture first picture)

It’s also unavailable on dev mod :

We can cleary see the animation, duration etc but not the background/position...
Am I missing something like it’s available somewhere? Or maybe is it a bug? But I can’t figure where to get this datas beside using a Plugin, and my goal is to mot use a plugin at all
here are the only datas I can get :
{
"trigger": {
"type": "ON_CLICK"
},
"actions": [
{
"type": "NODE",
"navigation": "OVERLAY",
"transition": {
"type": "DISSOLVE",
"easing": {
"type": "EASE_OUT"
},
"duration": 0.800000011920929
},
"resetVideoPosition": false
}
]
}
