Seller central handover from an agency

Hi guys! I have just started a new job yesterday. I’m going to have a meeting with the agency that was doing my company’s amazon from past 2 years. What do you guys think should I ask them as they are going to handover everything? I’m fairly familiar with amazon seller central but I have done amazon wholesale in the UK not the private label so its just me being nervous and just wanted to make sure I get everything I could from them in the handover meeting. The amazon account is for US and UK market, please help a bro out Many thanks
