I think Coinmarketcap has some requirements for the new tokens. They will add the token details once it listed on two or more exchanges which are on coinmarketcap list. CGCX is new so it might take some time.
But I takling about exchange volume and listing to coinmarketcap, not about token. Their exchane not showing on coinmarket. While GBX Digital Asset Exchange for example listed already there (in few month after exchange launch). As for token they need to have 10k+ usd daily volume for listing on CMC.
When they launched exchange? Do you know exact launch date? It seems take some time for showing on coinmarketcap or devs must contact them personally. For GBX exchange its tooks around few month I think (may be around 2 month after launch). Or may be they have more daily volume? As I know coinmarketcap have min limit for coins or tokens (10k daily min limit). But what about listing exchanges? Does they have min limit too?
I dont know about any special requirements for exchanges, but getting listed on coinmarketcap doesnt change the fundamentals (good exchange, token is pretty stable in this bear market, already multiple trading pairs, ...)
