For which one? You can just click on the link and it will bring you to the chat

no... the link goes to the website to download the APP

Yes but if you already have the app it will say “open app to continue” and it will automatically bring you in the chat when you click on ‘open’. @suyi01

Aah I can't get into the Line group. I downloaded the App already but it doesn't let me join a group.

Ah perfect. Thank you.
