How to set up a Hebrew font given as four .ttf files defining four variants: regular, bold, oblique, and bold & oblique, using babel+lualatex?

Question

I have downloaded four .ttf font files for the Hebrew language. The files define variants of the same font. The variants are: regular, oblique, bold, and bold & oblique. My LaTeX document uses the babel package as the language manager, and lualatex as the typesetting engine. I have placed the four .ttf files in my working directory. How can I set things up in such a way that the following document uses my newly downloaded font?

\documentclass{article}

\usepackage[bidi=basic]{babel}
\babelprovide[main,import]{hebrew}
%\babelfont{rm}{?}

\begin{document}

עברית\\
ֿ\textbf{עברית}\\
\textit{עברית}\\
\textit{\textbf{עברית}}\\
\textbf{\textit{עברית}}

\end{document}

Following Ulrike Fischer's hint, here's one way of setting up a main Hebrew font using babel's \babelfont command, when the four font files are in the Fonts subdirectory of the working directory, and are named myfont-regular.ttf, myfont-italic.ttf, myfont-bold.ttf, and myfont-bold-italic.ttf:

\babelfont[hebrew]{rm}[
   Path = Fonts/ ,
   Extension = .ttf ,
   UprightFont = *regular ,
   BoldFont = *bold ,
   ItalicFont = *italic ,
   BoldItalicFont = *bold-italic
