I am looking for the way to open file with my app to import some data in react-native app
However, I did find anything!
For example, I have an CSV file, and I want to open that with my React Native app to import some data in app from the file.

How can my app listen for particular file from email?

I found one npm package but I think it’s not enough what I am looking for.

Reproducible Demo

I don’t have a demo code but I can explaing here…

See the file is for map.me and in screenshot they got an option to import file in particular app.
looking for something like this.

As per this documentation I tried this but my app is still not detecting csv.

This is not a supported feature. Here is my last look at what would need to change to enable such a feature. Share images from Dropbox/Google Photos into Expo app?
