Export audio files via “open to:” from Voice Memos application

Question

I have the same question as “Paul” posted here: It is not possible to export audio files via “open to:” from the Voice Memos application - there are no answers to this topic yet.

Essentially, I'm trying to make it simple: After recording a voice reminder in iOS, I select "Open with" and from the pop-up that appears, I want to be able to select my application.

I tried everything I could think of and experiment with LSItemContentTypes without success.

Unfortunately, I do not have enough reputation to comment on the existing post above, and I am very desperate for a solution to this. Any help is greatly appreciated, even just to know if it is feasible or not.

Thank!
