MS Graph Api Colorize Range in Excel - fill missing

[martinlammers]

I am trying to colorize a row in an Excel Sheet.

My C# Code looks like that:

var formatRequestBody = new WorkbookRangeFormat
{
    Fill = new WorkbookRangeFill
    {
        Color = "#FFF00"
    }
};
await graphClient.Drives[driveId]
    .Items[FileId]
    .Workbook
    .Worksheets["table1"]
    .RangeWithAddress($"A{row.Index + 1}:H{row.Index + 1}")
    .Format
    .PatchAsync(formatRequestBody);

I get the error: The argument is invalid or missing or has an incorrect format.

Based on the endpoint, the code should be like ...Format.Fill.PatchAsync(body)

But the Fill request builder is missing in the SDK.

...
.Format
.Fill
.PatchAsync(formatRequestBody);
