const sdk = await SDK.New(providerEndpoint)
const Alice = 'This is a random seed phrase please do not use it';
const account = new Keyring({ type: "sr25519" }).addFromUri(Alice)
const key = "MyAwesomeKey"
const result = await sdk.tx.dataAvailability.createApplicationKey(key, WaitFor.BlockInclusion, account)
if (result.isErr) {
