Obtaining accounturi of existing account

[silverwind]

For a DNS CAA record, one can specify accounturi with a value like https://acme-v02.api.letsencrypt.org/acme/acct/1234567890.

Is there a way to extract this value from a existing acme.sh account registration?

The docs mention:

If your ACME client does not record the account ID, you can retrieve it by submitting a new registration request with the same key.

Any suggestions how to do that? I'm not sure what "key" refers to here.

I found it in the variable ACCOUNT_URL in ~/.acme.sh/ca/acme-v02.api.letsencrypt.org/directory/ca.conf.
