Forex Brokers Accepting MPESA Instant Withdrawal (Lowest Dollar Exchange Rate in Kenya)

Hi everyone, I am trying to figure out how to deposit money to Exness using MPESA without dealing with third-party merchants. Are they still the best option for instant deposits, or is there a better Deriv MPESA deposit agent out there right now? Also, which broker currently has the lowest dollar exchange rate brokers in Kenya when withdrawing profits? The spread on the USD/KES rate has been crazy lately.
