@fivetran-reneeli thanks for working on this PR and getting this new variable included! Generally this PR is looking good and I just have a few documentation related changes I would like you to make before approving.

Additionally, please add more details to your validation section of the PR template when not relying on our validation tests. I don't believe validation tests are needed for this change, but a quick screenshot will really help to provide more confidence to the claim that the variable works as expected.

For example a screenshot like the following highlights that the variable is working as expected and the default config is matching the expected results from before the changes.

Thanks @fivetran-joemarkiewicz ! And yeah for validations, I left the variable I had tested with in our internal notes but definitely could've screenshotted what I was looking at since there's no PII, noted for future reference.

[fivetran-joemarkiewicz]

LGTM, be sure to regenerate the docs before moving to release review. Thanks @fivetran-reneeli!
