Salesforce Integration - PD > SF

I was able to integrate Salesforce with PagerDuty using the package in the AppExchange. The integration SF > PD is working fine, but the PD x SF is not working. I’m getting this error when I try to enable the webhook in the PagerDuty configuration in Salesforce.

Error:
(403): Invalid Permission

PS: I have the PagerDuty Administrator license in Salesforce and a Full User license in PagerDuty

Hey Renato - Any update if you were able to fix this? If so, can you please share how you were able to? Getting the same error.
