Well, ewe sticker works great! You need to download your own stickers though. How it works is download a bunch of stickers from online (I used this place https://www.flaticon.com/ ), select a directory in Files (I made a new one called EweSticker), move all the downloaded stickers there, go to the app, press reload stickers. Also enable the keyboard. Now to access stickers (you'll still be on your default keyboard, HeliBoard for me) go to a messaging app, press and hold the space bar, select EweSticker and get your stickers!
