[gusty oar]

Hello 👋 I want to make something like that

"entity_doll": {
"type": "custom",
"size": [
30,
30
],
"renderer": "live_horse_renderer",
"bindings": [
{
"binding_name": "#entity_id"
},
{
"binding_name": "#form_text",
"binding_name_override": "#entity_id"
}
]
}

I use this but entity doesn't load in My form how can I fix it can someone tell me? 🤔
