How to implement SSR in custom transparent shader

If anyone could help me implement SSR in custom HDRP transparent shader, I will be very greatful.

You really need custom shader for this? HDRP 10 supports SSR on transparent if you enable the feature support for it.

I don’t want a custom shader, just to implement HDRP built in SSR in a older shader (code), that doesn’t have SSR
