Add property x-ms-notification-content to path

[davidchanmaximizer]

Hi Everyone,

I am working on a webhook of MS power automate.
the final result is wants to add "x-ms-notification-content" to a path using attribute annotation.
I tried with IOperationFilter and IDocumentFilter but they are not the place I want to add.
can anyone help?

"/repos/{owner}/{repo}/hooks": {
"x-ms-notification-content": {
"description": "Details for Webhook",
"schema": {
"$ref": "#/definitions/WebhookPushResponse"
}
},
"post": {
"description": "Creates a Github webhook",
"summary": "Triggers when a PUSH event occurs",
"operationId": "webhook-trigger",
"x-ms-trigger": "single",
"parameters": [
{
"name": "owner",

},
{

"in": "path",
"description": "Name of the repository",
"required": true,
"type": "string"
},
{

"in": "body",

}
}
],
