Workflow-webhook not tied to user

Hello!

We are developing applications in AWS (sorry, guys), and some workloads require posting to Teams channels using webhooks via Workflows (the new webhook way). We are also using webhooks to notify in Teams when Github actions finish or need interactions. However, when creating the webhook in Workflows it only seems possible to tie the webhook to a regular user. Are there any ways to use a Service Account / Service principal as the webhook/workflow owner? Using a regular user account as the webhook owner is a major drawback, eg. the need to rewrite all webhooks if the user quits the company and is disabled in Entra ID.
