I recently added a document picker to my NativeFileDocuments module. There is an issue with the Market Place registration. Be sure to click the Releases tab and then download the latest version from there. The default download button will download a really old version.

2 – Create new button ‘Call nanoflow’ use now ‘Take picture’ Action and configure it picture source : Camera or as you like
3 – now you can take photo
