Bybit API plugin

Hi, Could sombody / anybody dev api plugin for Bybit or OKX (or both)? Thing is that Binance (plugin available, Thank You) has no adequate demo environment. They have testnet (mock), but this looks so weird / not corresponding to the live environment at all and others, with plugins, are so low on daily derivative volume (https://coinmarketcap.com/rankings/exchanges/derivatives/ > sort by volume) so i think I can not get adequate volume input for demo testing. Thank You, L

Hi, indeed, community would appreciate.
