[QDS FlowView] Adding Action Areas and Transitions

https://doc.qt.io/qtdesignstudio/studio-flow-action-area.html

> Right-click the flow item in the 2D view and select Flow > Create Flow Action in the context menu.

cannot find " Flow > Create Flow Action" on .ui.qml which is used for FlowItem.

I also tried on the FlowView side, but the Flow seems unclickable.

then I drag and drop the FlowItem to FlowView and click the FlowItem shows inside FlowView the Menu has " Flow > Create Flow Action"

Missing steps:
1. Drag & Drop FlowItem to FlowView

2. Need to guide the users to click "FlowItem" shows in FlowView but not the FlowItem file or the blank space in FlowView

sometimes resizing FlowItem in FlowView will make FlowItem become a dot...

after creating ActionArea and FlowItem, I cannot identify which one it is because as you can see they all become red rectangles...

unclear what this means
> Note: To connect components to signals, you must first export the components as aliases in Navigator. To create and release connections, select Open Signal Dialog in the context menu.

after reopening the FlowView file the size seems be changed automatically. 

delete the transition line also delete the ActionArea which is very inconvenience
