How do you enter reasons when annotating an assessment using RecaptchaEnterpriseServiceClient?

[hjrobinson]

When I try to include reasons when annotating an assessment I always get this error:

Error: 3 INVALID_ARGUMENT: Invalid reason.

For example I might use the following:

const response = client.annotateAssessment({
 name:projects/111111111111/assessments/11111111111111111,
 annotation: "LEGITIMATE",
 reasons:["REASON_UNSPECIFIED"]
});

My node version is 16.19.0 My npm version is 8.13.2
