Apple IDP works in Hosted Login UI but fails with invalid_client error when using /v2/idp_intents AP

Hi team,

Apple IDP works in Hosted UI but fails with invalid_client using /v2/idp_intents API.

Config verified:

Domain: zitadel.4ja.ai
IDP ID: 331378047389270019
Apple Client: com.zitadel.ai
Team: 9X8D92Q95L
Key: NA25Z44LK4
Callback: https://zitadel.4ja.ai/idps/callback ✓

Issue:
API generates authUrl correctly, but Apple returns oauth2: "invalid_client" on redirect to failureUrl.

Hosted Login works perfectly with same config. What's different for IDP Intent API?

Thanks!
