render_offsets is deprecated, how do I fixed the looks of items?

[rustic plover]

I have 32x size of texture of my items, how do I fixed its look on third and first person if render_offsets is deprecated? Do I need attachables? If yes, how do I exactly do it? Need samples.

Is render_offsets deprecated? I still use this

"minecraft:render_offsets":{
    "main_hand":{
        "first_person":{
            "scale":[0.02, 0.02, 0.02]
        },
        "third_person":{
            "scale":[0.05, 0.05, 0.05]
        }
    }
}
