How to add a first page footer different from default one in NPOI - Docx?

I'm generating a docx file using NPOI 2.5.2 and I stuck with headers/footers for first page. I'd like to have a first page custom footer and start numbering pages from the second one.

Here is my code for the first page footer:

// First page
doc.Document.body.sectPr = new CT_SectPr();
var footer = new CT_Ftr();
var footerParagraph = footer.AddNewP();
footerParagraph.AddNewR().AddNewT().Value = $"FIRST PAGE CUSTOM FOOTER";
var footerPar = new XWPFParagraph(footerParagraph, doc);
var parsFooter = new XWPFParagraph[1];
parsFooter[0] = footerPar;
var headerFooterPolicy = doc.GetHeaderFooterPolicy();
if (headerFooterPolicy == null)
    headerFooterPolicy = doc.CreateHeaderFooterPolicy();
headerFooterPolicy.CreateFooter(XWPFHeaderFooterPolicy.FIRST, parsFooter);

Here is my code for the default footer with page numbering:

// Other pages
footerParagraph = footer.AddNewP();
footerParagraph.AddNewR().AddNewFldChar().fldCharType = ST_FldCharType.begin;
footerParagraph.AddNewR().AddNewInstrText().Value = " PAGE ";
footerParagraph.AddNewR().AddNewFldChar().fldCharType = ST_FldCharType.separate;
footerParagraph.AddNewR().AddNewFldChar().fldCharType = ST_FldCharType.end;
footerPar = new XWPFParagraph(footerParagraph, doc);
parsFooter = new XWPFParagraph[1];
parsFooter[0] = footerPar;
headerFooterPolicy.CreateFooter(XWPFHeaderFooterPolicy.DEFAULT, parsFooter);

With the code above I could not see the first page custom footer but the page numbering in every page. What am I doing wrong?

I found this similar question but I could not find addNewTitlePg method in NPOI.

And is there any appropriate documentation with examples about NPOI?

Here is my code with the first footer working. (using NPOI 2.5.3)

var doc = new XWPFDocument();
using (var sw = File.Create("fileformat.docx"))
{
    
    XWPFParagraph p1 = doc.CreateParagraph();
    XWPFParagraph p2 = doc.CreateParagraph();
    XWPFRun r1 = p1.CreateRun();
    XWPFRun r2 = p2.CreateRun();


    r1.SetText("The quick brown fox");
    r1.AddBreak(BreakType.PAGE);
    r2.SetText("Next page: The quick brown fox");

    doc.Document.body.sectPr = new CT_SectPr();

    var policy = doc.CreateHeaderFooterPolicy();
    var ctSectPr = doc.Document.body.sectPr;
    if (ctSectPr.titlePg == null)
    {
        ctSectPr.titlePg = new CT_OnOff() { val = true };
    }
    var firstFooter = policy.CreateFooter(ST_HdrFtr.first);
    
    var paragraph = firstFooter.CreateParagraph();
    var run = paragraph.CreateRun();
    run.SetText("First page footer...");

    var defaultFooter = policy.CreateFooter(ST_HdrFtr.@default);

    paragraph = defaultFooter.CreateParagraph();
    run = paragraph.CreateRun();

    paragraph.Alignment = ParagraphAlignment.RIGHT;
    paragraph.GetCTP().AddNewR().AddNewFldChar().fldCharType = ST_FldCharType.begin;
    paragraph.GetCTP().AddNewR().AddNewInstrText().Value = " PAGE ";
    paragraph.GetCTP().AddNewR().AddNewFldChar().fldCharType = ST_FldCharType.separate;
    paragraph.GetCTP().AddNewR().AddNewFldChar().fldCharType = ST_FldCharType.end;

    run = paragraph.CreateRun();


    doc.Write(sw);
    
}
