What I'm missing is how to separate the coordinate and point name for each point separately and put them inside a list

Here is a tutorial showing how to do something similar with the MIT Map using a csv:
[NP.png] National Parks ... display Markers, calculate distances to Markers and determine closest Marker using the MIT Map Component

The Tutorial
This tutorial demonstrates how to use the MIT Map component to display a large number of run time location Markers, calculate the distance from the Android device to all the displayed locations and display that information. A bubble sort creates a list of locations in ascending distance from the device. The first item in the calcul…
You probably could do something similar with your Bing Map.
A heads up. that might make a difference in how you code your app.
Be aware, the Bing Maps api is being retired .
Bing Maps SDK for Android and iOS is deprecated and will be retired. Free (Basic) account customers can continue to use Bing Maps SDK for Android and iOS until June 30th, 2025. Enterprise account customers can continue to use Bing Maps SDK for Android and iOS until June 30th, 2028. To avoid service disruptions, all implementations using Bing Maps SDK for Android and iOS will need to be updated to use Azure Maps Web SDK by the retirement date that applies to your Bing Maps for Enterprise account type.
The overview page for the Bing Maps SDK for Android and iOS section contains links to information about Bing Maps keys, license and terms of service and to the different topics covered such as getting started with Android and iOS, map control...
This may cause Bing Map users an issue next year

From which directory did you try to pick the file?
From an Android point of view there are an → Internal Storage and an → External Storage .
1. Internal Storage
The Internal Storage can only be accessed with a rooted device.
1.1 The app package is saved in
/data/data/<packageName>/
In order to be able to debug your app, AI2 saves the assets for → Companion on devices with
Android ≥ 10 (API ≥ 29):
/storage/emulated/0/Android/data/edu.mit.appinventor.aicompanion3/files/assets/
Android < 10 :
/storage/emulated/0/Android/data/edu.mit.a…
To read non media files which have been created by other apps you have to use SAF... to pick one of those files i.e. a text file of your choice from shared storage I think you also can use the filepicker component... I'm not 100% sure, because I did not test this...

Try putting both files in the same directory, do they both work / not work ?
two file are in the same path : / internal storage /DOCUMENTS/
I note that
In the emulator the text in the first file copied and give me
the second file not copied
After exporting apk file and try the two file the same error message for two files
and nothing copied
to plot the csv coordinates.
