[Python] Decorator in fastapi which is able to capture path param

In python, lets say I have fastapi API like so:

@router.put("/{workflowID}", response_model=WorkflowResponse)
async def update_workflow_endpoint(
workflowID: int, workflow: WorkflowUpdateRequest, db: AsyncSession = Depends(get_db)
):
... // Remaining code


I want to write a decorator which gets the path parameter workflowID. Like so:

@allowed_perm('WF_ADMIN', {workflowID})

So it gets two parameters - A string WF_ADMIN and the value of workflowID path param.

For ex: if API was called like so: /5, then I want the decorator to be internally get the value of 5.

How can this be done? I'm trying to build my permission module, and although I know this can be done using dependencies, I wanted to know if the same can be done via decorators.
