Webhook subscription Graduation issue

I tried adding the subscription and then cancelling it several times. There were no errors. I can see the endpoints in the Analytics showing the GET/POST/PUT/DELETE subscriptions. However, I can still not pass the graduation.

I found lots of other users were having similar issue and they were manually graduated. My client id is: Z3FNci2NTvWsi4B-4T725Q
Can I get it graduated.

Thanks in advance.
