Application avatar size for Forge

Hey guys,

Kindly let me know the requirements for an avatar used in applications built with Atlassian Forge. Every time I set an avatar for my application in the Developer console section, after uploading the avatar (a PNG file with a transparent background), it appears blurred after refreshing.

Where can I find any information about the requirements an avatar should meet to avoid being blurred after uploading?

It should be similar with the marketplace doc which is 144x144 pixel
