ArubaOS-CX Switch-Aruba CX 4100i Radius Login SSh with OKTA

We configured the AAA radius for ssh login using OKTA.We can see the push notification but we aren’t getting access to the switch . Below is the configuration. Please, let me know if i am missing anything? Also, How can we send back Aruba VSA attribute or specific role back with admin-Role

radius-server host port 1912 acct-port 1912 key plaintext

aaa authentication allow-fail-through

!

aaa group server radius OKTA

server port 1912

!

aaa authentication login default group OKTA local

aaa authentication login ssh group OKTA local

aaa accounting all default start-stop group OKTA

!

Thanks,
