Error message is not clear when trying to access a cloud secret when the user is not logged in

What went wrong?

While trying to access a cloud secret when not logged in, I got the following error message:
RUN <the command I ran with the secret>: unauthorized

As it's common for a secret to be a password or access token, the user might think unauthorized indicates there is a problem with the password/token, when in fact it's earthly that cannot access the cloud secrets provider to fetch the secret.

Try to access a secret via RUN --secret or
RUN --mount=type=secret,id=<SECRET_PATH>,mode=0400,target=/root/.ssh/id_rsa \<your command\>

while not logged in

VERSION 0.8

PROJECT earthly-technologies/core

FROM alpine
ARG --global SECRET_PATH=<path-to-rsa-secret>

secret-flag-test:
    RUN --secret SECRET_PATH=$SECRET_PATH echo hello

mounted-secret-test:
    RUN --mount=type=secret,id=$SECRET_PATH,mode=0400,target=/root/.ssh/id_rsa echo hello

When logged in: earthly +secret-flag-test and earthly +mounted-secret-test works as expected

When not logged in it fails, e.g.: EARTHLY_TOKEN=fake earthly +secret-flag-test
What should have happened?

The error message should be more explicit about not being able to access the secret.
Perhaps if the user is not logged in the error message should state it explicitly

When the user is logged in but the secret is not found - earthly tells the user the secret could not be found
