Throttling Incoming Emails in Lindy: Solutions for 504 Errors

Hi everyone! I have a Lindy set up to grab order documents from incoming Outlook emails. The monitored inbox often receives multiple forwarded emails at once (usually 3–5). When that happens, I get 504 errors (see attached screenshot). I tried adding a timer after the trigger, but the issue isn’t with processing after the trigger, it’s with throttling the incoming email load itself. Is there a way to handle or throttle this directly from the Lindy side?
