It's changed a few times, and if you've watched any tutorials that have the Mask Designer as a tab in the PiP Designer, those videos are really old as they were made with a version like PD14.
By PD17, the mask tool had become its own separate designer which was accessible from the Designer button that would appear above the timeline when a clip was selected.
In PD365, you now have to select the timeline clip then click on the Edit button that will appear. You'll see a list showing Adjustment and Tools, and you'll see the Mask Designer about halfway down the Tools list.
Also, if you ever want to find where something is or how it works, just open the onlin help system by hitting the F1 key. You can than use the Index or Search tools to find the tool, effect or designer you're looking for.
