I'm quite late to the party, but something similar like this I asked a
few days ago (06.12.2020):
https://sourceforge.net/p/openvpn/mailman/message/37170200/
I proposed a generic way to send whatever you like over the
control channel. A plugin could be triggerd by hooks which react on
this generic push command. The plugins for all different OS and UIs
could trigger messages in new windows or network managers.
Your wish is to send a message, mine was to send a certificate. A
generic push command could achive both, as long the plugin is
installed.
echo could be a possibility, but fiddling with log files must also be
implemented (by a plugin?)
