Voicemail for Dual SIM

How do we set up voicemail for the second line (eSIM)?

At this point Is be happy if I can get both to use the same voicemail, but ideally I’d have 2 separate messages and message boxes.

All the previous questions I’ve seen relating to this just post some irrelevant link to the general eSIM setup that has no mention of voicemail, I expect the same will happen here, but will try anyway with the vague hope that someone actually has a solution by now.

Thanks
