Why don't you use the original KDE Plasma translations?

I had a look to the translation system but all the string for my mother language are to be done, that’s a massive job and this is already done by the KDE localization team.

This is their web https://l10n.kde.org/

And here you can see their progress here https://l10n.kde.org/stats/gui/trunk-kf5/team/

Why you do not to use this then?
