Website Performance Audit

Hey All,

I ran a website performance audit on my page and it was showing relatively low items in the page size breakdown, with the exception of one. I know this is a modern website builder that uses JS, but the page size breakdown lists the JS size at over 6 MB. I dont really have a frame of reference to compare that to, but the audit said it is too big. Can someone help me understand this? I appreciate any help!
