Recruting API Auth 401

Hi Personio Team,

I'm having trouble Authenticating with the Recruiting API https://api.personio.de/v1/recruiting/applications

I've tried calling the endpoint via postman and using the Try It! feature on the API doc page https://developer.personio.de/reference/post_v1-recruiting-applications

replacing my real data with dummy data this is the request I'm trying to send from the Try It! feature.

curl --request POST \
     --url https://api.personio.de/v1/recruiting/applications \
     --header 'Accept: application/json' \
     --header 'Authorization: Bearer abc' \
     --header 'Content-Type: application/json' \
     --header 'X-Company-ID: 12345' \
     --data '
{
     "first_name": "first",
     "last_name": "last",
     "email": "[email protected]",
     "job_position_id": 678910
}
'

I got the Bearer Token and Company-ID from the "Recruiting API Key" under https://{YOUR_COMPANY}.personio.de/configuration/api/credentials/management

is there anything I need to enable to have this endpoint/auth work?
I found a similar post on here which sounds just like the problem I am having https://developer.personio.de/discuss/6285495ddeba1100a8c4f5bc
is it possible the same problem is occurring here?

Cheers,
Nikolai
