The goal would be to click on the timeline -> create the item with the starting time in the point you clicked -> move to the right to edit the right edge time

Describe alternatives you've considered
For now I'm using the onCanvasClick to create a new item, select it using the selected props but unfortunately I'm the resizw/move doesn't work
