Multi-Inner-Hits doesn't seems to be available in Collapse

[LGabilly]

Please use the following questions as a guideline to help me answer
your issue/question without further inquiry. Thank you.

Which version of Elastic are you using?

[x] elastic.v7 (for Elasticsearch 7.x)
[ ] elastic.v6 (for Elasticsearch 6.x)
[ ] elastic.v5 (for Elasticsearch 5.x)
[ ] elastic.v3 (for Elasticsearch 2.x)
[ ] elastic.v2 (for Elasticsearch 1.x)

Please describe the expected behavior

Inside a collapse I which to have multiple inner_hits. Like : Collapse inner hits

Please describe the actual behavior

It seems, there can only be one single Inner_hits field inside the collapse field

Any steps to reproduce the behavior?

elastic.NewCollapseBuilder("user").
    Field("name.keyword").
    InnerHit(elastic.NewInnerHit().Name("one")).
    InnerHit(elastic.NewInnerHit().Name("two"))

Yes, looks like a missing feature in CollapseBuilder at least.
