Sending userID in OIDC login request
When redirecting user from application to Okta for authentication is it possible to send user ID to Okta through OIDC request that way user ID is pre-populated for user to login?
In Our case application instance is Salesforce if that helps.

Yes, if you have access to custom authorization servers you will be able to add a custom claim to the token. See these instructions.
