[Request]: Remove origin app from list of share destinations

### Plugin

share_plus

### Use case

When you share an pdf file from app you can share it back to the app (if your app supports the type). But in that case share dialog never finishes. So Its not possible to share another file, unless app is restarted.

### Proposal

There are options that you can exclude the app of origin from the list of possible destinations.
If that is not viable a shareXfile without the return value could also solve this issue.
