Have You Heard This Śiva Chant?

[mangalavara]

Namaste. There is a nonsectarian mandir in my city that does livestreams on Sundays, and every time I watch their livestream, I hear a Śiva chant that I cannot find any results for online. So, I wonder if perhaps it is their own composition.

The chant goes like this:

जय शिव जय शिव जय शिव ॐ
जय शिव शिव जय जय शिव ॐ

Jaya Śiva Jaya Śiva Jaya Śiva Oṃ
Jaya Śiva Śiva Jaya Jaya Śiva Oṃ

Have any of you heard this before?

Thanks.
