Can I SR for a shiny Mew in the Crystal Caves

I’m trying to shiny hunt mew and I think the only way how is to soft reset with full odds in the crystal caves. Is this how you are supposed to do it?

Yep. You save before interacting with it and you soft reset until it is shiny

I started doing it already and are at 401, but thanks for the clarification!
