How to get it on iMessage?
Response from developer
Here is how to use it: 1. Start a new iMessage. 2. Tap on the App icon. 3. Tap on the four oval on the lower left corner to open the app drawer. 4. You should see the Tennis Stickers pack. Select a sticker and add it to your message. If you do not see the Tennis Stickers pack, tap on the Store icon to access the iMessage App Store. Select Manage and turn on Tennis Stickers. If you need more instructions, please see this Apple Support page. This works just like any other stickers: https://support.apple.com/en-us/HT206906
