download an excel in asana in python

Question

import asana
import json  
from six import print_
client = asana.Client.basic_auth('personal token')
me = client.users.me()
print_("me=" + json.dumps(me, indent=2))

personal_projects = next(workspace for workspace in me['workspaces'] if workspace['name'] == 'workspace name')
projects = client.projects.find_by_workspace(personal_projects['gid'], iterator_type=None)
print_("personal_projects=" + json.dumps(projects, indent=2))

for project in projects:
    #print_ ("gid", project['gid'] )
    if project["name"] == "Test":  # name of the searched project 
        print_ ("")
        print_ ("Project", project['name'] )
        project_id = project['gid']
        project_tasks = client.tasks.find_by_project(project_id, iterator_type=None)
        for task in project_tasks:
            #print_("Tasks=" + json.dumps(task, indent=2))
            print_ ("  Task ", task['gid'], ":", task['name'] )
            task_id = task['gid']
            task_subtasks = client.tasks.subtasks(task_id, full_payload=True)
            for subtask in task_subtasks:
                #print_("    Sub-tasks=" + json.dumps(subtask, indent=2))
                print_ (subtask['gid'], ":", subtask['name'] )

In that project (Test) as a task there is an excel saved, I would like to be able to download that excel. Continuing with that code, I don't know if it's possible.

Thank you
