Found an issue while setting up channel URLs with puiHidePPMTabs=on in the channel URL and doesn't seem to appear to work for Modern UX (MUX) channels. Works OK for Classic channels but not MUX.
Steps to Replicate:
Expected Result: The Channel hierarchy to hide module tabs
Actual Result: The Channel hierarchy shows the module tabs
Example: Menu tab for Hierarchy workspace is shown within the menu tab of Pages.

You need to ensure that when adding the &puiFullscreen=on, &puiHidePPMTabs=on or &puiHideHeader=on parameters, the first parameter should be preceded by a '?' mark, not an '&' mark.
Changed the Channel URL to the following:
../../../../../pm/#/hierarchy/5xxxxxx/investments?puiHidePPMTabs=on&puiFullscreen=on
