Create webhook using oauth app 2.0 token doesnt work

[Ohad Hoffmann]

Hey, I'm trying to create a webhook using rest API call with an oauth app 2.0 token
the app token can get accessible resources , projects, issues and more - but when trying to create a webhook (scope permission is given) I can 401 response

this is my curl -

curl --location 'https://api.atlassian.com/ex/jira/<cloud_id>/rest/api/2/webhook/2' \

--header 'Accept: application/json' \

--header 'Content-Type: application/json' \

--header 'Authorization: Bearer <token>' \

--data ' {

"url": "https://my-app.example.com/api/v1/webhook/",

"webhooks": [

{

"events": [

"jira:issue_created",

"jira:issue_updated",

"jira:issue_deleted",

"comment_created",

"comment_updated",

"comment_deleted"

],

"jqlFilter": "issueKey != NONEXISTENTPROJECT-1"

}]

}'

I also tried this guide I found -
https://www.merge.dev/blog/guide-to-webhooks-with-examples-from-jira
after doing all of it, I managed to create a webhook and get 201 - but no webhook was found in the UI section - https://my-test.atlassian.net/plugins/servlet/webhooks#

not sure what else I can check
appreciate your help
