If you see the FAQ it states:

We have temporarily disabled Messenger customer chat plugin on Safari 12 while we work to resolve issues.

Found a fix, you can enable the plugin through the plugin list in your plugin installed list.

I was trying to enable it through the apps directory list after searching for it.

So consider it a small bug, but a fix for sure!!

It works @golam Samdani

Thanks ??

Yes I need to report this as well.
