PageSpeed Insights - Largest Contentful Paint element 2,090 ms

[ManKaveStore]

Website is: https://mankave.store/

I've been trying to figure out how I can improve a few problems I'm having with my page speed. I've tried editing some of the liquid code, but I'm also hesitant because I don't know liquid very well, or how to properly navigate through the Shopify folders properly. I understand the liquid sections are rendering the images, but I don't know how to access to actual images other than from inside the actual 'Theme Editor'. 

Here is what I see from PageSpeed Insights regarding this issue. I've converted all images to webp format from simply converting and adding the newly converted images into the 'Theme Editor', but it didn't seem to make too much of a difference. I've also tried adding CSS code to just give it height/width: 100% parameters, but didn't seem to do anything. Please help,

I've been Googling them for the past couple days with no avail, reason why I posted the help question. Was hoping for a specific solution for 'Largest Content Paint element,' and once I actually can fix this problem, moving onto the next.  I mean there is stuff on Google, but it doesn't really help me implement it into the Shopify liquid code.

Do you know how you can specifically fix the error for my main slideshow picture, and just that? I'm sure once I know how to do one, I can figure out the rest.

Ignore this above reply, there are agencies or freelancers that just  spam generic replies in hopes of gettings jobs on this forum. I feel like its specific to the pagespeed forums, I don't see this sort of blatant spam on other shopify sub forums.

I suggest your report spam answers like these, as they just are annoying and bad for the community.

So looking at your site on your site, yeah your lab score for LCP isn't supper low, but isn't super high, and its only your lab score. I suggest you wait untill  you have a live user score before worrying about the LCP, if you see your users have bad LCP then worry about it.

More critical than the score itself is that your banner image doesn't seem to even be visible on mobile, this one

Its affecting your LCP score but you aren't even benefiting from it on mobile.
