My page speed is very bad

Hi Guys, According to Google page speed my site is very slow on loading.
I have used Asset optimization etc, but when it comes to things like moving files to the footer etc I am totally lost, I have no idea which files I should move . From what I can see Elementor is taking a lot of time and maybe loading files it does not need too.
Any help would be great. I have enabled site access for you to take a look.
