Per the error message, you can add those permissions, but your app must have a privacy policy in order to use them. You might want to take a look at the expo documentation on deploying to app stores:
https://docs.expo.io/distribution/app-stores/
Additionally, a number of developers have reported warnings from
Google if their app does not have a privacy policy, since by default
all Expo apps contain code for requesting the Android Advertising ID.
Though this code may not be executed depending on which Expo APIs you
use, we still recommend that all apps on the Google Play Store include
a privacy policy as well.
If you need help figuring out how to host a privacy policy, here is a good idea and guide:

If you need help generating a privacy policy, consider Firebase's generator:
