[help wanted] not able to connect via pd-live-react to my pagerduty account

[icvdok]

Hi, I'm trying to run locally a pd-live-react instance but I got back an "Unauthorized Access".
I've cloned the repo in a Linux machine.
I've registered in PagerDuty an OAUTH app.
I've started the pd-live-react passing the client ID and secret of the OAUTH app,
Running the pd-live-react in a browser I'm able to insert my credential and get the disclosure. Then I got following error:

Unauthorized Access

User is not permitted to access this instance of PagerDuty Live. Please contact the associated site owner for access.
