How to get List of other tokens in the same wallet address (minted)

i have one wallet key(public key) and i want to send 1 sol to another walletkey. so how to write code?

var transaction = new web3.Transaction().add(
web3.SystemProgram.transfer({
fromPubkey: from.publicKey,
toPubkey: to.publicKey,//i want to put here my own wallet key so how to write code ?is there any syntax for this?
lamports: web3.LAMPORTS_PER_SOL / 100,
})
);
