I use the Metadata API and the Apex wrapper to create an AuthProvider and NamedCredential after the installation of my managed package app.

MetadataService.NamedCredential cred = new MetadataService.NamedCredential();
cred.fullName = 'MyCred';
cred.label = 'MyCred';
cred.allowMergeFieldsInBody = false;
cred.allowMergeFieldsInHeader = true;
cred.authProvider = 'MyKeycloak';
cred.generateAuthorizationHeader = true;
cred.oauthScope = 'api refresh_token';
cred.principalType = 'NamedUser';
cred.protocol = 'Oauth';
cred.endpoint = apiEndpoint.trim();

The problem is the Authorization is still in Pending status as a user seems to manually Edit and Save the Named Credential to trigger it.

Is there a way I can trigger that by my code when I insert the NamedCredential?
