Hi Joseph, *(
Sorry for the late reply. Yes,even though the page is not generated in SCHLIX, what you can do is as follows:
1) Copy & paste the content to the WYSIWYG editor - use the last button on the 2nd row. See screenshot here: https://www.schlix.com/documentation/v2/content-editing/most-frequently-used-editor-buttons.html
2) Set the permission on the "Permissions" tab under "Who can read this page?". If necessary, create a new user group first.
Hope this helps.
