Hello!,

I’m building an app, and I need help implementing a feature using NFC and deep linking.

Here’s my use case:

- I want users to scan an **NFC tag** that opens a specific screen in the app.
- The NFC tag contains a URL like this:  
`https://myapp.adalo.site/certificado-cliente?key=CCLATELIER0001`
- That URL should open a screen in Adalo (called `Welcome screen`) **and pass the value of `key`** as a parameter to that screen.

❓**My question is: How can I capture the `key` parameter inside the screen and use it to show information (e.g. filter a list or display a record)?**

I’ve tried the Deep Linking route setup and added a custom route name (`/key-customer`), but I don’t see an option to add a screen parameter or input to capture the 'key` value.

Could you please confirm:

1. Does Adalo currently support receiving URL query parameters like `?key=XYZ`?
2. If yes, how can I access and use them inside the target screen?
3. If not, is there a workaround or roadmap feature I could rely on?

Thanks in advance for your support!
