How to delete a workflow by it's name?

[ahmaadaziz]

I am using typescript and I use the function putWorkflow() to create a workflow just like how the docs suggest it. However, it returns nothing, meaning I do get back the newly created or updated workflowId which is required to delete or get it in the future.
For now, I am completely star-struck as to how I am supposed to get that ID and be able to delete my workflows.
