Date Range Picker

Hello,
i am new to caldera forms and just build my first one.
My first issue is, i need a date picker to set a date range (for a room reservation).
Now i read something about the Date Range Picker AddOn, but i can’t find anything about this except in this support forum.
Is that AddOn still available? That would be great!
If not, is there any solution how i can solve a date range with caldera forms?

Thanks for your first help!!
Kind regards,
Henning
