Arabic letter not aligned properly

Question

I am trying to write an official letter in Arabic using the package newlfm but the text is aligned from left to right instead of right to left. Here is my code:

\documentclass[11pt,stdletter,orderfromtodate,sigcenter]{newlfm}
\newlfmP{headermarginsize=20pt}
\newlfmP{addrfromskipbefore=0pt}
\newlfmP{addrtoskipbefore=-25pt}
\newlfmP{dateskipbefore=0pt}
\newlfmP{sigsize=0pt}
\newlfmP{sigskipbefore=30pt}
% 
\newlfmP{Headlinewd=0pt,Footlinewd=0pt}

\usepackage{etoolbox}

\makeatletter
\patchcmd{\@zfancyhead}{\fancy@reset}{\f@nch@reset}{}{}
\patchcmd{\@set@em@up}{\f@ncyolh}{\f@nch@olh}{}{}
\patchcmd{\@set@em@up}{\f@ncyolh}{\f@nch@olh}{}{}
\patchcmd{\@set@em@up}{\f@ncyorh}{\f@nch@orh}{}{}
\makeatother

\usepackage{graphicx}
\usepackage{fontspec}
\usepackage{setspace}
\usepackage{polyglossia}

\setmainlanguage[calendar=gregorian,hijricorrection=1,locale=morocco]{arabic}
\setotherlanguage[variant=british]{english}

\setmainfont{Amiri}

\namefrom{سعيد}
\addrfrom{%
\\193 الصويرة 44000
\\الهاتف: \LR{\textenglish{06~00~00~00~00}}
}

\addrto{%
\textbf{إلى السيد: المدير بالنيابة للمدرسة العليا للتكنولوجيا بالناظور}\\     
}

\dateset{\today}

\greetto{الموضوع: شغل منصب أستاذ التعليم العالي مساعد}

\closeline{التوقيع:}

\begin{document}

\begin{newlfm}

\end{newlfm}

\end{document}

And below is the resulting document:

I would appreciate it if someone can help me fix the alignment (make it right to left instead of left to right). Thanks.

You can use the letter document class with the layout=sectioning option of babel, instead of newlfm

You might be able to adapt this template, which requires LuaLaTeX 1.12 or later. (It would work in XeLaTeX, with a few changes.)

\documentclass[11pt]{letter}
\usepackage[bidi=basic, layout=sectioning.tabular, british]{babel}
\usepackage{fontspec}

\defaultfontfeatures{ Scale=MatchLowercase,
                      Ligatures=TeX,
                      Renderer=HarfBuzz }

\babelfont{rm}
          [Scale=1.0, Ligatures=Common, Language=Default]{Libertinus Serif}
\babelfont{sf}
          [Ligatures=Common, Language=Default]{Libertinus Sans}
\babelfont{tt}
          [Language=Default]{Libertinus Mono}

\babelprovide[import=ar-MA, main]{arabic}
\babelfont[arabic]{rm}
          {Amiri}
% Set \babelfont[arabic]{sf} here if needed.
\babelfont[arabic]{tt}
          {ALM Fixed}

\babeltags{english=british}

\signature{سعيد}

\address{
  {193 الصويرة 44000}\\
  {الهاتف:}\\
  \textenglish{06~00~00~00~00}
}

\begin{document}
\begin{letter}{\textbf{إلى السيد: المدير بالنيابة للمدرسة العليا للتكنولوجيا بالناظور}}
\opening{الموضوع: شغل منصب أستاذ التعليم العالي مساعد}

\ldots

\closing{التوقيع:}
\end{letter}
\end{document}

I attempted to simply copy and paste the Arabic from the question, and apologize for any errors.
