How to check the signing key of the installed product
After obtaining the certificate fingerprint of the installed app, check that it is the same as the certificate fingerprint of the signing key that it will be compared to.

Android API reference
To retrieve the information of other packages at API level 30 or higher, you must apply package visibillity.
The fingerprint of the signing key certificate can be checked on Play Console when using Google Play App Signing, and can be extracted using keytool, apksigner, etc. if you signed it yourself.
How to check the app source information of installed products
When an app is installed, the name of the store or installer where the app was installed is saved. This can be found in Settings > Applications > Application Information.
After obtaining the installer package name of the installed app, crosscheck with the package name on the store to check the app source information.

To retrieve the information of other packages at API level 30 or higher, you must apply package visibility filtering.
How to request to delete a product
The DELETE_PACKAGES (or REQUEST_DELETE_PACKAGES) permission is required for an app to have its own delete function. Because this is not a standard permission, users will be directed to the application information screen so that they can delete it directly.
