How can I get all equities in index?

Hi,

how can I get all equity in index?

for example)

0#.SPX in eikon's all RIC list.

It would be perfect if I can fetch with "/discovery/search/v1/" search API, but it seems advanced search app doesn't have that feature.

I tried to search thru https://apidocs.refinitiv.com/Apps/ApiDocs but no information there as well.

Thank you.
