Joomla Free extensions

I can't use the jooauto facebook plugin because I don't know what to do with it.
You want an Application Id, but I don't know which application you mean. Which application is it? What application should I set up on Facebook? Which? I don't know what you mean. Your link in the instructions for this application is not functional, no application can be accessed. I don't know what application to use there. Where can I get it, where should I set it up?

This cannot be understood from the instructions. I do not know what to do. Where should I get the ID and secret? I'm sending a picture of the error in the manual, so the link is not correct, there is no proper application.

This is useless when I have to set something up and I don't know where to find it.

Hello Nataša Řezníčková
Sorry for this problem. Problem because Facebook have updated link. Now you can go to site developers.facebook.com/apps/ and create Facebook application. You can see image prnt.sc/109tjtu
Or can you send me joomla admin and your Facebook account via contact form and we will help you install and config it
Best regards
