                    NotSupported: bybit fetchFundingRates() does               
                    not support future markets

And on the OKX exchange:

ExchangeError: okx fetchFundingRate() is only              
                    valid for swap markets 

And on the GATE exchange

gate fetchFundingRate() supports                
                    swap contracts only 

I tried to figure it out myself, but my level of code writing is 0 :D
