How to call a parameter and use it to access an object in JavaScript?

I have this function where I have 2 parameters, I use the "field" parameter to access an object but it takes it as an attribute of the object and does not refer to my parameter.

async id(modelo, campo){
    const data = await modelo.all()
    console.log(data)
    
    var idmayor = 0
    for (let i = 0; i < data.rows.length; i++) {
        const id = data.rows[i].campo;
        if(id > idmayor){
            idmayor = id
        }
        console.log(idmayor)
    }
    idmayor + 1
    return idmayor
}

Here it can be shown better that it does not refer to the parameter "field"

Thank you
