Hello, I'm new to Zoho Show. I picked this as an alternative to MS Powerpoint and I'm in it to make animated videos. I can't figure out how to get rid of this white background on the object I'm trying to animate  https://drive.google.com/file/d/1Wz6XFyeWV7-9NwalRw_VjrSODB_fonTW/view?ths=true. Is there any way to get rid of it? (Just so you know, the object is a PNG file.)
