Hi when trying out wrapping and issuing hash on blockchain, I keep getting this message:

========= NOTICE =========
Request-Rate Exceeded  (this message will not be repeated)

The default API keys for each service are provided as a highly-throttled,
community resource for low-traffic projects and early prototyping.

While your application will continue to function, we highly recommended
signing up for your own API keys to improve performance, increase your
request rate/limit and enable other perks, such as metrics and advanced APIs.

For more details: https://docs.ethers.io/api-keys/
==========================

Is there any documentation on how to update the api keys?

I found it.
Replacing:
const provider = getDefaultProvider("ropsten");
wtih:
const provider = new providers.EtherscanProvider("ropsten", "api key");
