This does not explain how to then make calls. Calls like this do not work:

try {

const transactionHash = await ethereum.request({

method: 'eth_sendTransaction',

params: [

{

to: '0x...',

'from': '0x...',

value: '0x...',

// And so on...

},

],

});

// Handle the result

console.log(transactionHash);

} catch (error) {

console.error(error);

}
