I'm sorry for not getting back to you sooner. Did you experience an issue with the check? Did you have to check if it was equal to true to make it work?

As far as I remember, I needed to add this to work. I couldn't have the same env right now because of that I couldn't retry it. But it works when I did like this. But maybe the check is unnecessary and example update is enough 😅
