How to call function RelatedUserAccessPermission to fill check boxes b

I work on .NET core 7 MVC razor page . I face issue I can't fill check boxes Id StockTake and ShelfLabelPrint by using ajax request to this function RelatedUserAccessPermission

URL below I run it on browser to access function RelatedUserAccessPermission

 public JsonResult OnGetRelatedUserAccessPermission(int UserId)
        {

            var UserAccess = _db.UserAccess.ToList();
            return new JsonResult(UserAccess);

        }

so I need to call function OnGetRelatedUserAccessPermission from page model using ajax request .

so I need to make ajax request for that URL ?handler=RelatedUserAccessPermission

Access Rights 1 meaning it check true

Module Code 1,2 values of Id StockTake represent id 1 and ShelfLabelPrint represent id 2 based on UserId 1220

on AddUserAccess.cshtml
 

<button id="FillCheckBox" type="submit" class="col-sm-1 btn btn-primary">Submit</button>
        <div class="form-group row">
            <label for="user-id" class="col-sm-1 col-form-label" style="font-size:15px;font-family: 'Open Sans', sans-serif;font-weight: bold;">User ID</label>
            <div class="col-sm-3">
                <input id="useraccess-id" asp-for="UserAccess.UserId" type="text" class="form-control" style=" margin-left:10px;font-size:15px;font-family: 'Open Sans' , sans-serif;font-weight: bold;" />
            </div>
        </div>
        <input id="StockTake" type="checkbox" asp-for="UserAccess.MODULECODE" value="1">
        <label for="lblStockTake">Stock Take</label>

        <input id="ShelfLabelPrint" type="checkbox" asp-for="UserAccess.MODULECODE" value="2">
