Does the Forerunner 245 have a Heart Rate Variability test when connected to heart rate strap?

Does anybody know? It is not mentioned in the owners manual of the FR245 but this test is mentioned in the FR45, Or is this covered in the Stress score?

I have the idea that the R-R interval is what is needed and optical doesn't give this but the modern chest straps do.

Exactly, and I have connected a chest strap to my watch, but I cannot start such a test, as it is not in the settings. But I guess it should be somewhere as even the Forerunner 45 supports it according to its manual?
