Missing Logo for Chiliz Chain and CHZ native token

### What is this about?

What is this about?
As a user adding chains and tokens to metamask
I want to see logos of the tokens
So that I feel more secure about what tokens I have and I can easily differentiate them.

Could we add the logos of Chiliz so that when someone adds The Chiliz Chain to metamask it has a logo for CHZ the native token.
Chain ID: 88888
Currency: CHZ
Logo: https://assets-staking.chiliz.com/images/assets/Chiliz.png
