(Edit) I was able to easily apply from a different country than my permanent residency and know many others with the same story. Thought it was universal. Glad the group is able to correct this info and note that it is particular to your citizenship where you are able to apply.
No treatment plan. Just appointments booked, also had a consultation via zoom and a paid receipt. Clinic gave an official stamp like seal. Approved Jakarta within 4 working days.
