Ajax Begin Form Api Route is different in 10.1

Question

I'm using XP 10.1 & XC 10.1

The following way used to work in earlier versions of XP.

using (Ajax.BeginForm("SaveContactUsFormData", "ContactUsForm",
                                new AjaxOptions
                                {
                                    HttpMethod = "Post",
                                    OnSuccess = "OnSuccessContactUs",
                                    OnFailure = "OnFailureContactUs",
                                    LoadingElementId = "divLoading"
                                }))
{    
        @Html.AntiForgeryToken()
    <button type="submit">Submit</button>
}

But now it renders the form action url as - /api/cxa/ContactUsForm/SaveContactUsFormData
I'm expecting the url should be - /api/sitecore/ContactUsForm/SaveContactUsFormData. Is that correct or has it changed for commerce (or xp 10.1).

The controller method is not triggered on debug and the button click is doing a postback instead of an asynchronous call.

UPDATE:

The code in the action method does execute without any errors.

Set "IsCxaSite" to true in "Site Grouping" item for that SXA site and then try to trigger cxa api's.
