Build me an Xposed apk module

We need an apk which is will be installed on a phone with Android 7.1.2. that phone will have root access. That apk will run via xposed [login to view URL] if you have a better way to run that app without exposed module then it is up to you. /////////////////////////////////////////////////////////////////////////////////////////////////////////////////// Alter camera input or can select image locally when official app only allow submit image using camera. I have using one app that when it need document id verification it must scan using phone camera. what i need is xposed module that can add function to manually select image from my phone, instead of take picture using camera . the app is " mpay walet " search is google playstore.
