Hey Namita, for reusing existing workflows, you can use Invoke Workflow File activity. Invoke Workflow File activity lets you invoke or add another workflow file into your current workflow and you can also Import or Edit Arguments present in that workflow. So it's really a very efficient way of reusing the workflows. Invoke workflow is mainly used for creating big and complicated projects. In such cases, you can simply divide your complex sequence into parts and create them. Later you can just test them and invoke them into one Main file. This will make your development much more easier.
Now to get a better idea about invoke workflow activity, see this example:
1. Create a flowchart with some condition in it like checking for correct name. This is your first workflow.
2. Now create another workflow showing some other functionality like desktop recording. This will be your second workflow.
3. Now in first workflow, call Invoke Workflow File and provide the path of second workflow in it.
4. Finally, just run the program, and you will be able to see both the workflows being execute
