After the successful installation, you have to run these commands in the Adobe Commerce root directory.
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy
After running the commands, you have to flush the cache from the Adobe Commerce Cloud admin panel by navigating through->System->Cache management as shown below.

If a user wants to translate their module from English to German then they need to follow the path app/code/Webkul/MpRmaSystem/i18n in their unzipped Magento Marketplace folder and will get a CSV file with the name “en_US.csv”.
Now they will rename that CSV as “de_DE.csv” and translate all right side content after the comma in the German language. After editing the CSV, save it and then upload it to the path app/code/Webkul/MpRmaSystem/i18n where they have installed Adobe Commerce on their server.
