If you want your application to be used only on devices with a front camera, you can specify this by adding front-facing-camera to the application the necessary functions .
However, if the application has sufficient functionality when working on devices without a front camera, then it is probably better not to indicate this feature. From the documentation :
You should include keys only for those functions that are absolutely necessary for your application. If your application can use the missing functions, avoiding the code paths that use these functions, do not include the corresponding key.
