Transparent background on my icons are grey

Hi all,
I want to display round icons on a table. The background around the circle is transparent, but it's displaying as grey.

Is there a solution or should I update all pictures with a white background?
Thanks a lot.

Hey @Pierrick81!

I'm not aware of a way to do this at the moment, but I've raised it with the dev team!

In the meantime, one more temporary solution you can try is the following custom CSS:

   background-color: #0000; 

Thanks @Kabirdas !
I'll try that.
For now, I've just reuploaded all icons with white backgrounds.
