Not seen any change in interface except Upgrade message

[WebDweller]

I successfully ran below commands as per README file.

composer require firebear/importexportfree
php -f bin/magento setup:upgrade
php -f bin/magento setup:static-content:deploy
php -f bin/magento cache:clean

However, only change I see is a Upgrade message bar on the Export & Import pages of Admin Panel.
