Please add option to search for group in B2C tenant

We have a need to search for group using "endsWith" and/or any part of the group (via $search) instead of the only option "startsWith" or "eq" for B2C tenant.  Please add support for this option.

var requestOptions = new List<Option>
{
    new HeaderOption("ConsistencyLevel", "eventual"),
    new QueryOption("$search", $"\"displayName:UniqueName\""),
    new QueryOption("$count", "true"),
};

var groupResult = await client.Groups.Request(requestOptions).GetAsync();
