GT Metrix Errors

Hi dear Support Team

1-Serve static assets with an efficient cache policy
There are lots of .mp4/woff/woff2/png files that have no CACHE TTL or just 1week ttl

but in my .htaccess file I see these : A315576000 means 180 days to expire

### marker BROWSER CACHE end ###

But GTmetrix could not detect that !

2-remove unused Java Scripts / this file belongs to Litespeed chache plugin and was repated 6 times on Iteams in Gtmetrix :
*Use passive listeners to improve scrolling performance
*Reduce unused JavaScript
*Avoid long main-thread tasks
*Reduce JavaScript execution time
*Avoid serving legacy JavaScript to modern browsers
please see the images :

https://prnt.sc/DxIfdR9-gln2
Is there any suggestion to solve that ?

3-Based on Litespeed dos not support Perload the font yeat , I found the code for that and suould put in htaccess file

Header add Link "</wp-content/themes/betheme/fonts/fontawesome/fa-solid-900.woff2>; rel=preload; as=font; crossorigin=anonymous"
Header add Link "</wp-content/themes/betheme/fonts/mfn/icons.woff?31690507>; rel=preload; as=font; crossorigin=anonymous"

but it’s not working and still get error of Avoid chaining critical requests
Can you please tell me or guid me what should I do for this one ?

Thanks alot
I love you Litespeed Cache Plugin and Team
