Hi, due to some reasons I have got a bug using the onesignal. Actually, I don’t want to purchase the thunkable pro but my app must have onesignal and for that I have used the onesignal web push. The error was that I am using a web viewer in which the user should subscribe but the onesignal says wrong environment and to do that I must need a deep link 🔗. when the user clicks on subscribe he should directly go to the app by a deep-linking process and I need some link which makes the website to open my app. Can this be possible and there is anything like a deep-linking [@staff](https://community.thunkable.com/groups/staff) please reply ---
