unable to use openid

i'm trying to setup OpenID configuration on my helm chart.

i've set up this vars

frontend:
extraEnv:
- name: OIDC_CLIENT_ID
value: "value"
- name: OIDC_ISSUER
value: "address"
- name: OIDC_LOGIN_BUTTON_TEXT
value: "Sign in with Platform"
apiServer:
extraEnv:
- name: ALPINE_OIDC_ENABLED
value: "true"
- name: ALPINE_OIDC_CLIENT_ID
value: "value"
- name: ALPINE_OIDC_ISSUER
value: "address"
- name: ALPINE_OIDC_USERNAME_CLAIM
value: preferred_username
- name: ALPINE_OIDC_TEAMS_CLAIM
value: groups
- name: ALPINE_OIDC_USER_PROVISIONING
value: "true"
- name: ALPINE_OIDC_TEAM_SYNCHRONIZATION
value: "true"

i've replate issuer and client_id with a placeholder for this ticket

but i don't see the openid button on login


could someone help me with this config? PS is a configuration using keycloak.
