Webhook for Mattermost (no bot accounts available on my Mattermost account)

[JeanYvesQueignec]

Hello,
I am currently stuck to send a notification from ArgoCD to a Mattermost Channel I have configured with an incoming webhook (note that I have no possibility to add a bot account in Mattermost)
I have tried to elaborate a ConfigMap to use it as hereunder ( I have tried to align with webhook config proposed in doc - example on Send Slack)

On ticket here #176 I see the URL from webhook following by /api/v4/post ? not working as well from my side....

Do we have to add something in annotations section from the app ?
Is it necessary to add a trigger ? or is it OK for a first step to use this CM ?

Do you have any clue to fix it ?

Regards,
Jean-Yves
