The like component lets you like or dislike items in your app.
When someone hits like, the component passes a value of +1 to the sheet. When someone dislikes an item, the component sends a value of -1 to the sheet.
The like component requires User-specific columns. Without User-specific Columns, every time a user likes an item – that item will show as 'liked' for all other users. With User-specific Columns – each user will experience their own data for that component - allowing the like or dislike value to be unique to them.
