FastAPI OpenIdConnect

Hey folks, I am trying to make the following to work:

from fastapi.security import OAuth2PasswordBearer,OpenIdConnect

oidc_scheme = OpenIdConnect(
    openIdConnectUrl=f"{os.getenv("ZITADEL_BASE_URL")}/.well-known/openid-configuration"
)

async def get_zitadel_principal(introspected_token: Annotated[dict, Depends(oidc_scheme)]):
    zitadel_id = introspected_token.get("sub")
    # other code

from fastapi.security import OAuth2PasswordBearer,OpenIdConnect

oidc_scheme = OpenIdConnect(
    openIdConnectUrl=f"{os.getenv("ZITADEL_BASE_URL")}/.well-known/openid-configuration"
)

async def get_zitadel_principal(introspected_token: Annotated[dict, Depends(oidc_scheme)]):
    zitadel_id = introspected_token.get("sub")
    # other code

Then I visit the docs and try to use "OpenIdConnect (OAuth2, implicit)" mode, but I keep getting the following issue:

{
  "error": "unauthorized_client",
  "error_description": "The requested response type is missing in the client configuration. If you have any questions, you may contact the administrator of the application."
}

{
  "error": "unauthorized_client",
  "error_description": "The requested response type is missing in the client configuration. If you have any questions, you may contact the administrator of the application."
}

See the screenshots, I am not sure what else to try by now, I tried multiple combinations of response type, grant types (with implicit and not) ... I am just not sure what else to try by now and who is in fault here
