The plugin includes .po/.pot translation files. I recommend using Loco translate and settings the text domain and filename-prefix to “fslm.”
- Go to the page Loco Translate > Plugins.
 - Click on FS License Manager.
 - Click on Advanced.
 - Set the “File prefix” as “fslm”.
 - Set the “Text domain” as “fslm”.
 - Save.
 - Click on “Overview”.
 - Click on “New language”.
 - Select your language.
 - Click on “Start Translating”.
 - Translate the text.
 - Save.
