Glossary with terms and definitions in English and Chinese

I have two files, main_EN.tex and main.CN.tex, that hold the same content in English and Chinese respectively. They share the same preamble and the glossary file. The glossary is created with the glossaries-extra package. I am new to this package and feel a bit overwhelmed with the number of options and all the intricacies.

So I am not sure how to add to the glossary Chinese definitions for terms and acronyms, as well as Chinese translation for the terms.

Ideally, I would want to have something like this:

newglossaryentry{charger}
{
    name-english={charger},
    name-chinese={充电器},
    description-english={A device for charging mobile phones},
    description-chinese={给手机充电的设备}
}

newacronym{usb}{USB}
{
    translation-english={Universal Serial Bus},
    translation-chinese={通用串行总线}
}

Then I want to be able to pull definitions for a selected language.

This thread proposes a way, but I cannot make it work with Chinese, and it looks a bit complicated.

Can you please suggest the best way to do it?

So far, I have tried adding translations with the package translations. See the MWE code below or see the actual MWE.

my-preamble.sty

NeedsTeXFormat{LaTeX2e}
ProvidesPackage{my-preamble}


usepackage[colorlinks=true]{hyperref}

usepackage[english]{babel}
% Import local copy of `babel-zh.ini`
babelprovide[import]{chinese}
usepackage{translations}
DeclareLanguage{chinese}

% Allow Chinese typesetting
usepackage{ctex}

usepackage[acronym]{glossaries-extra}

makeglossaries

usepackage{my-preamble}

selectlanguage{english}

section*{In English}

The gls{charger} has three glsxtrfull{usb} ports.

printglossaries
end{document}

main_CN.tex

documentclass[10pt]{article}
usepackage{my-preamble}

begin{document}
selectlanguage{chinese}

section*{在中文中}

gls{charger}有三个 glsxtrfull{usb} 端口

printglossaries
end{document}

Result

As you can see, the sections Glossary and Acronyms show proper translations, but the term label is not replaced with the actual term in the body of the document. I also get multiple "Undefined Control Sequence" errors.

Any help will be very much appreciated!

Edit:

In a comment, Venez proposed an idea to use the iflang package. It works perfectly!

See the MWE code below or see the actual MWE.
