does polaris offer a time picker for embed apps? if not, then what is the alternative
Good question.
I don’t believe so but you can handle this in a few different ways, it just depends on how much flexibility you want to give.
For example, if there’s only X number of pre-allotted slots to choose from, you can simply show buttons or clickable divs that represent the 3 different choices.
Alternatively, you can use an select dropdown to choose the hour of the day, and another to choose the minute (perhaps in 15 or 30 minute intervals).
