If you used a privacy chain for bridging it shouldn't pose a problem, if it does, it'll create a hit on flag on their system and they'll simply ask for source of funds. It's rare they get hits unless you use sanctioned mixers DIRECTLY with that wallet or straight up wanted to use monero.
Assuming standard AML procedures︀ are in place they'll ask for source of funds regardless of your use of a︁ privacy platform so this shouldn't be an issue if the client has his affairs in︂ order.
The use of sanctioned software like mixers that have been openly banned by the︃ U.S./EU regulators can make the entire deal fall through however, while monero is just grounds︄ for additional checks. If you use mixers, make sure you trade those funds and swap︅ them in various DEXes using different wallets. 99% of the time this is enough to︆ avoid problems as most blockchain software is made to trigger flags only when interacting with︇ a wallet that has directly used a mixer but not the subsequent wallets thereafter (Unless︈ it's law enforcement that's after you then it'll be a human connecting the dots lol).︉
