You can in the settings of car MBUX and Mercedes Me App (click on bottom right icon Triangle,map page, click on top right Settings, scroll down to bottom Navigation with Electric Intelligence, at the bottom is Mercedes Me Charge, click Enable all chargers will indicate now accept payment via MBUX, Mecedes Me App or Mercedes Me Charge Card, and can verify if you select charge point to see Details of Charge point and how to pay, to be honest it is hit and miss, MBUX states failed Authentication process with charger, then Mercedes Me App or Mercedes Me Charge will work !!! pot luck. choose only Mercedes Me Charge points or All Charge Points, whilst using Mercedes Me Charge Points, individual charge points of one station if it consists of multiple chargers will indicate on the charge point by a blue Upwards Pointing Arrow indicating the power of the charger more arrows shown higher charge point, normally one arrow for 7.4kW or lower and more than 2 Arrows indicate Fast Charger 50 kW plus... Instavolt Network charge points works fine with my Mercedes Me Charge Card in MY EQA Prem Plus, but fails with MBUX somehow to authenticate process... told the dealership, not interested stating it lies with Mercedes Me Charge support, same answer from Mercedes Me App support
Mercedes Me Charge are responsible to inform Mercedes HQ of information regarding charging failures throughout Europe from my emails.. Have to say early adopters will suffer glitches, bad software, firmware (MBUX) car, and technical issues. Hope this helps.
