Question: iOS signoutsilent

[Excel1]

I implemented the oidc-client.ts in my vue capacitor app. To logout i use the signoutSilent.

async function logout() {
      await userManager?.signoutSilent();
  } catch (error) {
    console.error('OIDC logout error:', error);
  }
}

On Android everything works perfect. But on iOS i got logged off but not redirected:

Redirection to URL with a scheme that is not HTTP(S)
Failed to load resource: Redirection to URL with a scheme that is not HTTP(S)

Redirect to: myapp://lougout

How does the library work with signOutSilent. Is this more a capacitor problem?
