The actual credentials prompt implementation finishes a previously started credentials prompt prompt_id with
ECredentialsPrompterImplClass:ECredentialsPrompterImpl:process_prompt() by a call to this function.
This function should be called regardless the prompt was or was not cancelled with
cancel_prompt. Once the prompt is finished another
queued is started, if any pending exists. Use null credentials for cancelled prompts,
otherwise the credentials are used for authentication of the associated Source
.
