I can’t find the api , elm_image_animated_play_set, on API References

Hello, Dear. I’d like to make a animation when the app was launched. So, I was searching forum history , I got below APIs from you. elm_image_animated_play_set(obj, EINA_TRUE); elm_icon_animated_set(obj, EINA_TRUE); but, I can’t find how to use them on API References. Please let me know how can I use these with gif or png. Thanks.
