My PR application has been approved and I received the IPA letter last week.

I am currently living outside of Singapore and will need to return to attend an in-person appointment at the ICA.
Can anyone advise how long I will need to plan to be in the country to attend the medical appointment, receive the results of the HIV and TB tests, apply for the insurance then attend the meeting at the ICA?
Am I right in thinking I need to wait 7 days for the insurance to be approved before the in-person meeting? Do I also need to allow to wait a few days after the ICA appointment to pick up the IC card once it has been produced?
I applied in May 2024, which I believe was under the old system.
Any advice or experience welcomed. Thank you!
