Form Repeat new feature to access items

Hi,

I’ve been following this thread: Access Form Repeat data and was happy to see that a new feature to access items within form repeat was added in Wappler 5.0.3: Wappler 5.0.3 Released

However, I still don’t see how to access form repeat data - I tried using syntax like form_rpt_id[index_id].subcomponent_id.selectedvalue but that didn’t work.

Anybody manage to use the new feature successfully, or is able to link some documentation for how to use it (the release notes are pretty bare on detaill)?
