Where are language file fields for shipping estimator plugin

-- HikaShop version -- : 4.1
-- Joomla version -- : 3.9.8
-- PHP version -- : 7.2.19
-- Browser(s) name and version -- : chrome
-- Error-message(debug-mod must be tuned on) -- : NONE

where can i find the language file fields for
SHIPPING_ESTIMATION
SHIPPING_ESTIMATION_FROM_TO

it's in en-GB.plg_hikashop_shippingestimation.ini

but i can't find where that file is after installation ( i purchased it), and those fields do not appear to have been added to the usual EN-GB language file.

Thanks...

Hello,

The language file is where Joomla store it during the installation ; It's in the administrator part but the place is not important.
Since Joomla handle the installation, it also handle the override process.
So in your Joomla backend, under the "Extensions > Language > Overrides" you can add your overrides for these entries.
