How to call IElasticClient.Index() when the type that we are indexing is generic

When I have an explicitly typed object, I have no problems indexing. For example,

EventObject e;
IElasticClient client;
client.Index(e); // perfectly valid

However, I have a class where the type is generic. This is my class

class FantasticClass<INDEXCLASS>
{
    IElasticClient client;
    public FantasticClass(IElasticClient c)
    {
        client = c;
    }

    public INDEXCLASS Add(INDEXCLASS entity)
    {
        client.Index(entity); // can't compile!
        // or
        client.Index<INDEXCLASS>(entity); // can't compile!
    }
}

How do you index with Nest when the class type is inferred?

The issues with it not compiling are due to the class missing the declaration of what type INDEXCLASS is this should resolve that error: 

class FantasticClass<INDEXCLASS> where INDEXCLASS : class

Also the Add method has a return type of INDEXCLASS however nothing is returning in the method. Either change it to void or return the entity variable after it has been indexed.
