How to Clone a Flow
In contrast to export, the clone function creates a copy of the flow within the same organization, appending "CLONE" + date and time to the name.
To illustrate, if the original flow is named 'Flow1', the cloned flow will be named 'Flow1_CLONE_Wed Jul 26 2023 16:57:22'.

Please note that the clone function reverts the versioning of the flow back to version 1, which means that all version history data is lost.
