Can Jira Cloud Automation incoming webhook trigger use x-www-form-urlencoded?

[Eric Law]

Is there any way to get the incoming webhook automation trigger to accept payloads with Content-type application/x/www-form-urlencoded ?

Documentation regarding Atlassian/Jira Cloud Automation Triggers
for Incoming Webhooks can be found here:

https://support.atlassian.com/cloud-automation/docs/jira-automation-triggers/#Incoming-webhook

While this webhook can be used in reference to existing issues, there is an option:
'No issues from the webhook'

It is not until you try to configure this trigger in the Rule builder that it says that it implies it only takes a JSON payload when it says:

(i) Please ensure that the request you send explicitly includes the header set to .
For example if you're using :
curl -X POST -H 'Content-type: application/json' ...

Is there any way to get this webhook to accept Content-type: application/x-www-form-urlencoded ?
