Disabling pdf and docx export, but allowing "send by e-mail" export

I noticed that once I disable the “export to pdf” and “export to docx” options within the user rights management, the “send by e-mail” option is eliminated from the Q&A export menu as well, despite the fact that the latter option is enabled within user rights management.

Is there a way to avoid this?

I would like to simplify the whole export experience by leaving the “send by e-mail” option only.
