Online task creation

I wanted to create a task which I did using python code, it ran perfectly but my supervisor said that task should be online.

While sourcing for ways, I saw that I could open a Pavlova account, sign in and upload the images and code. I did that but the next step which is to run the code, I don’t seem to find any button to run the code.

I need an easier explanation on how to perform my task online (the task is designed using code since I’m not too proficient with the builder)

Thanks for the anticipated responses and suggestions
