Sankaku Channel/Delete a gif

I want to delete one of my gif's https://chan.sankakucomplex.com/post/show/5023726 since I didn't extract the audio before the other one.

Instead of deleting (there's nothing wrong in it tbh, 'cept you didn't tag the anime or characters), I approved it, so you can upload an audio-less version either way.

By the way, that's not a gif, that's an MP4.

And how long does it take to approve a gif? I have 26 and would like to upload some more plz.
