Ansible mattermost custom icon_url

[Michael]

According to the Ansible mattermost module documentation; the mattermost message sender's icon is a url that defaults to the redhat icon. It can be customized but a url to the to the image needed should be provided.

I didn't think this made sense but i'm hoping that i can find some helpful explanation as to how i can use my custom emoji :loudspeaker: without having to upload any images to anywhere and define permissions to the image.

Example from the Ansible website:

- name: Send notification message via Mattermost all options
  mattermost:
    url: http://mattermost.example.com
    api_key: my_api_key
    text: '{{ inventory_hostname }} completed'
    channel: notifications
    username: 'Ansible on {{ inventory_hostname }}'
    icon_url: http://www.example.com/some-image-file.png


Thanks in advance!!
