Also didn't find it in the keyboard emoji list. Even after pressing the "add to my emoji" button.

You have to create the Emoji set first or subscribe to one that has it. You can use https://emojis-iota.vercel.app/ to subscribe to different sets.
Then they will show up in your Reaction setup screen
