How to use custom day labels in v-calendar?

[thany]

This was working in v2:

<template v-slot:day-label-header="{ date }">
  // Do something with date or whatever and poop out a <v-btn>
</template>

Not anymore in v3. So how do I translate this to vuetify 3?

I did see something in the documentation about "exposed" and an entry genDays, but what is meant with exposed? Exposed how & where? And what can we do with exposed things in this regard? There is no documentation on what "exposed" means, or even so much as an example.

Maybe genDays isn't even what I need. It doesn't matter what I need - I just need to achieve my goal, and that is to apply custom styling (could be a class or whatever, I don't care as long as I can apply some sort of custom style) to a day header based on business logic. Currently I haven't got a clue how to get there, and so anything would be better than what I currently have, which is nothing.

This feature has not been added back yet. There is a PR open that includes many of the slots and click events, but needs slightly more polish and then approved.
