Configuring for Mac Mail

I am new to LibreOffice. I am trying to configure to use Mac Mail. I configured the email program as “/System/Applications/”. However when I try to send a document File>Send email is grayed out.
What is the problem?

Hi itredler,

Without knowing the software versions involved, I could not simulate your finding.

Below is a screenshot using Version: (X86_64) / LibreOffice Community
Build ID: c21113d003cd3efa8c53188764377a8272d9d6de
CPU threads: 8; OS: Mac OS X 13.2.1; UI render: default; VCL: osx
Locale: en-US (en_KR.UTF-8); UI: en-US
Calc: threaded

and I set up the mail app, Version 16.0 (3731.400.51.1.1), following the standard prompts on macOS, 13.2.1 (22D68) running on a 2020 intel MacBook Pro.

Here is a photo showing that one must go to send> an email document…

Good Luck with fault finding.
