Re: Using babel package and setting babelfont

ChatGPT suggestions is to add the following to the document preamble:
```
\usepackage{fontspec}
\AfterPackage{babel}{%
\babelfont[hebrew]{rm}[Script=Hebrew]{Arial}%

}

```

OR

```
\usepackage{fontspec}
\usepackage{etoolbox}

\AtEndPreamble{\babelfont[hebrew]{rm}[Script=Hebrew]{Arial}}

```

which seem to work.
But I am a bit suruprised to learn that LyX forces me to do such workarounds.
