External API compatibility with Custom connectors in Power Platform

Question

We want to build a custom connector inside Power Apps which integrate with external API. and for this integration we will use the Oauth2.0. Now the external API provides these details for the Authentication:-

Token name - ********************

Grant Type - Authorization Code (With PKCE)

Callback Url - https://first.localhost:9000/auth

Auth Url - https://auth.********.net/oauth2/authorize

Access Token Url - https://auth.********.net/oauth2/token

Client Id - *****

Code Challenge Method - SHA-256

so is this info enough/sufficient to configure the custom connector's OAuth2.0, as on the custom connector we will be asked to provide these info:-

so what is the missing info in the external API that we need to get and ask the vendor about it?

Thanks
