Pytezos: structuring call for FA2

Question

Can you guys help me correctly structure a call to the update_operators in an FA2? I tried everything single combination I can think of, and it still doesn't work

It says the structure should be like this:

Typedef
$update_operators:
        [ $update_operators_item, … ]

$update_operators_item:
        { "add_operator": $add_operator } ||
        { "remove_operator": $remove_operator }

$remove_operator:
        {
          "owner": address,
          "operator": address,
          "token_id": nat
        }

$add_operator:
        {
          "owner": address,
          "operator": address,
          "token_id": nat
        }

$address:
        str  /* Base58 encoded tz or KT address */

$nat:
        int  /* Natural number */

This was my final attempt and I'm stuck:

add_op = token.update_operators({
    "update_operators_item" : {
        "add_operator": {
            "owner": 'tz1...',
            "operator": 'KT1...',
            "token_id": 0,     
        }
    },
})

As @Groxan pointed out, update_operators entrypoint expects a list:

add_op = token.update_operators([{
    "add_operator": {
        "owner": 'tz1...',
        "operator": 'KT1...',
        "token_id": 0,     
    }
}])
