New Shift Planning repeat option available via API?

If you repeat a shift through New Shift Planning interface, it shows: "Every week on Monday until 02/01/2024"

Trying to repeat shifts weekly via the API.
repeat: 7 (weekly)
repeat_until: 2024-02-01
repeats_staff: 2 (with employees)

The shift is repeated, but New Shift Planning just shows "Repeat Options" and is greyed out instead of providing any details.
The same happens if I create the repeat through Legacy Shift Planning.
Legacy Shift Planning Shows Repeats 5 times [Weekly]

for the ones created through API and Legacy Shift Planning.

I did notice that legacy shift planning shows Repeats 5 times [ Weekly *new ] instead of Repeats 5 times [Weekly] on, so it seems like a new repeat option was added in New Shift Planning. Is that new repeat option available through the API?

Also checking with support to see why it isn't displaying the legacy options in new SP.
