Safari import extension problem

Has anyone else had problems with the Safari extension for the Lingq importer? I get the error that the application needs to be installed in the /Applications directory.
I’m pretty sure that I’m opening it from the Applications folder as you can see in the pictures below, but I am new to Mac so maybe the problem is me… Tried a bunch of times and I’m always getting the same problem so would like to know if it’s a problem with the extension itself or just something I’m doing wrong. Grateful for any help. Thanks!

You should have dragged and dropped that LingQ icon on the left inside the application folder. Then I think you click that application and it will ask you to add it to Safari and then I don’t remember.

I have it, it’s working. I just don’t use it because of the permissions but that’s another story.

That worked! Thank you so much
