Can't apply macro to ticket

[Lx4]

Hi,

I'm trying to apply a macro this way as shown in the readme with :
macro_result = zenpy_client.tickets.show_macro_effect(ticket, 12345)

I have the following error :

  File "/usr/src/app/manage.py", line 1783, in recurring_zendesk
    macro_result = zenpy_client.tickets.show_macro_effect(1, 12345)
  File "/usr/local/lib/python3.10/site-packages/zenpy/lib/util.py", line 111, in inner
    return func(*new_args, **new_kwargs)
  File "/usr/local/lib/python3.10/site-packages/zenpy/lib/api.py", line 1383, in show_macro_effect
    macro_effect._set_dirty()
AttributeError: 'Response' object has no attribute '_set_dirty'

Any idea?
Thanks
