Our WideVine configuration requires us to pass in a custom license certificate through a URL.
I see that, per https://developer.roku.com/docs/developer-program/getting-started/architecture/content-metadata.md , there is a way to pass this in as `serverCert`.
We want to validate our streams actually work first, and were trying to use the Stream/RAF Tester Tool. However, we don't see a way to pass in the serverCert.
Is there a way to do this with Stream/RAF Tester?
