Microsoft Graph Client SDK -filter groups by name

A rather simple ask but I'm having trouble converting my basic httpClient method of querying the Graph into the SDK method. I was using the following and it works fine:

    var filter = "IT";
    var response = await httpClient.GetAsync($"{webOptions.GraphApiUrl}/beta/groups?$filter=startswith(displayName, '{filter}')&$select=id,displayName");

...now I'm attempting to filter using the SDK as follows:

    var groups = await graphServiceClient.Groups
        .Request()
        .Filter($"displayName startswith {filter}")
        .Select("id, displayName")
        .GetAsync();

I've also tried .Filter($"startswith("displayName", {filter})) and other variants.

I'm getting an invalid filter clause error. Any ideas?

Apparently it occurs since the provided filter expression for Filter method is invalid, it could be validated like this:

var message = graphServiceClient.Groups
        .Request()
        .Filter($"displayName startswith '{filter}'")
        .Select("id, displayName").GetHttpRequestMessage();

The generated message.RequestUri will return the following value: 

https://graph.microsoft.com/v1.0/groups?$filter=displayName startswith '{filter}'&$select=id, displayName}

A valid filter expression needs to be specified like this:

.Filter($"startswith(displayName, '{filter}')")

In case if you want to switch to beta version for GraphServiceClient class, it could be specified like this:

graphServiceClient.BaseUrl = "https://graph.microsoft.com/beta";
