yes, sometime in coming SDKs it might have an affect, but currently it is not in use.
So the issue for you was that you used the wrong function, (shareAsync works fine, the also with text if you post in messenger, but not for wall posts for desktop).
if you want to post an image with text to the people/group you invite you shall use updateAsync, after chooseAsync.
If you want to know how the functions work you should look in the SDK References
