XRP wallet generation from xrpl js

[tuncatunc]

How can I generate xrpl seed from account keys using account_key below.
XRPL seeds start with s

const wallet = xrpl.Wallet.fromSeed(seed)
console.log(wallet.address) // 

    "account_key": {
        "ex_pub": "xpub6CALbNc6Py6VH6fHXrRFH6oG1nXBS8DLcwtaSrQmQ6iCoi5jmavvne6adr1AdAasqCfMY6QbrR4SjtwQTfMK1XktE3Y33ncQQ96aXrvNxWY",
