Site origin widget bundle removes visual editor button

I’m just starting to test this plug in which seems to work when I manually edit the page slug via the short code insert in the text editor.
But the button to add and choose pages is missing in the visual toolbar editor.
I disabled TinyMCE advanced in case that was the culprit but still missing it
with the native WP toolbar composer.
The most recent similar issue I found was this thread
https://ww.wp.xz.cn/support/topic/button-in-the-toolbar-of-tinymce-disappear-conflict-page-builder/

and I also I think narrowed it down to the Site Origins widget bundle. If I activate the Site original Page Builder that does not remove the add page button on the visual toolbar , but activating the accompanying SO widget bundle does remove it. So possibly this needs looking at again it there is a conflict that can be resolved at this end?
