Here you can import new option sets with attributes, export existing option
sets to modify and later import the modified version again. You must be in
Option Sets menu to use this functionality. If you do not see your Option sets or this feature is not working properly
then make sure you've launched it from Bubble. Your project -> Option Sets
-> Scroll down your option set list -> Click "Bulk Actions"
If you are importing a List of items, then separate the items with a pipe (|)
