I am I am trying to integrate with other organization, and the Authorization Servers tab within Security -> API seems to be missing, however the Authorization Servers tab is visible at my account ( Developer Edition).
note
authentication: Single Sign-On to Okta using OpenID

try by open-up okta case , may flag need to be enable from okta end..
Yes, I'd support what @BhaskarM.18336 (Customer) said: your company might not have that feature, or it might not be turned on, Support can probably tell you.
The Developer edition already has an authorization server built in, which is why you can see it there.
