How to translate the plugin ?

Hello Viktor my friend, hope you ar going well,
I didn't find how I can translate th eplugin. If i publish it on a french page the strings are in english, for example here www.agerix.fr/blog/comment-lia-generale-...ations-metier-agerix and if I publish it on a english page the strings are missing, example here www.agerix.fr/en/blog-en/how-general-ai-...-applications-agerix
I search in the file manager but I didn't find. If you tell me where they are I can share you a french translation.
Thank you for your answer and.. take care
