Clone a Power Automate Flow within a Solution

When you want to copy a flow within a solution, you do not have an immediate option in the UI. For simple flows you could use copy/paste within the Flow Editor. For more complex flows, you could try to "save as" the flow but it won't be added to the solution immediately. Another option is exporting the solution, copying the files locally and importing the solution again. But there is an easier and faster option!
