elementor table of content widget is not working

i am working on my website which niche is technology. i am trying to apply semantic seo on my site, so i decided to provide ease to my user. i add table of content widget to my site so that my user can browse a specific section in which he/she is interested. but my table of content links are not working, when i click on the link it’s not scrolling me to that specific section. i set my TOC for h2 and h3 tags. but in content h2 and h3 is not getting any id like “elementor-toc__heading-anchor-n” nor available in h2 tag or nor in span tag above of h2 or h3 tag.
