Content editing problem, SKT page builder

Dear RankMath team,
First of all thank you very much for your amazing plugin.
I am using SKT builder my website URL is http://www.royalsaffron.af
I have already finished the design of my website using SKT page builder.
Now the problem i am facing is that i am not able to edit content of my website to check the SEO score by rank Math as i can do with wordpress editor.
My pages have animitaion and nice design so i want to keep the current design and edit the content for 100 score.
I used to edit page using wordpress editor, i can only edit rich snippet, title, URL and meta description, but i am not able to edit content with wordpress editor to see the live Rank math Score on my homepage.
Please help and advise in this regard

Thank you very much
