Can't select Service Account authentication for Google REST API

Based on this forum thread, I expected to be able to create a new REST resource that authenticates on behalf of a Google Service Account. But I can't select that under the "Authentication" dropdown.

We're self-hosted on 3.52.7.

Hi @Auke_Booij Thanks for reaching out!

The feature is available by default on v3.75. I went ahead and manually added it to your account since you're not on that version yet. You can ensure it's enabled by going to Settings->Advanced->Click "Check key"

Let me know if you have any follow up questions
