'Missing' on field aggreagation is not available in Java Client

I am trying to do an aggregation on multi-terms fields and include the cases where there is no value for for fields. The missing property should handle that, but it looks like it cannot be set in Java Client co.elastic.clients.elasticsearch._types.aggregations.MultiTermLookup. Or is it somewhere else?

It happened to me but in another clause that did not have the parameter x. I opened an issue in git and waited for the Elastic team to add it. I believe you have to do the same.

I've hoped that I am missing something and won't need to wait for new version.
