hello , how to process the result 'listPrepsDetails'

[collery]

when i call listPrepDetails, it's return

{
        allOwnersConstraint: MUST_MATCH
        labelOwnerConstraint: null
        msku: 10-EJ7J-ZK6V
        prepCategory: SMALL
        prepOwnerConstraint: SELLER_ONLY
        prepTypes: [ITEM_LABELING, ITEM_POLYBAGGING]
    }

i want to set in my amzonProduct model ,

prepCategory SMALL
prepOwner: SELLER

but labelOwner what value ? NONE_ONLY or SELLER.。

"msku": "qtestKuzi241203",
"allOwnersConstraint": "MUST_MATCH",
"prepCategory": "FRAGILE",
"prepTypes": [
