OIDCProviderTokenEndpointAuth should be none by default for PKCE ?

[khamlaoui]

Hello,
First all, thanks for this great open source project!
For my use case, i configure the module with Auth code + PKCE, but i faced an error that i fixed by configuring the OIDCProviderTokenEndpointAuth to none.
Following your documentation the value of OIDCProviderTokenEndpointAuth "When not defined the default method from the specification is used, i.e. "client_secret_basic"".
But when we are using PKCE there is no secret, so auth to token endpoint should be none.
My question is: The default value for OIDCProviderTokenEndpointAuth when PKCE is used should not be none ?

Thanks for your answer
