It's not possible to un license an image but I've added an image credit to your account so you can select another image to use instead.
Hope this helps !!!
I just did the exact same thing & then licensed it again because I'm trying to figure out how to unlicense something.
I lost 2 image credits. Would you be able to add them back to my account, please & thank you.
Adobe ID is: [Personal info removed by Mod]
As advised previously, we do not have a way to undo this. Please ensure you select the 'Preview' option in future and only license the image when you are sure you want it. I have added a credit to your account as an exception.
Yes you are right, but it is very easy, especially as you have a
deadline to meet pressing the wrong button - I think Adobe should review
this procedure because after not just me to make this mistake - thank you
