Missing support for some interactive dialog element types date/datetime

[arnofo]

Summary

Support for some documented interactive dialogs element types are missing from the app :

• date
• datetime

(I believe file is not supported either but since it's a totally different scope with file uploads and such maybe it should have it's own issue opened ?)

Expected behavior

The app should render a correctly formatted field like the web version does and submit a correctly formatted date : ISO format for date and RFC3339 format for datetime. (according to the documentation)

Observed behavior

The app renders a plain text field (for both date and datetime) with no indication on format. Leaving the user guessing the format.

Thank you !
