problem exclude h2

Hello,

We want to exclude some of our H2 tag appearing on the TOC, so we use option Exclude Headings :

we input like this on the option Exclude Headings : *exclude-toc* – image > https://file.io/CEGXcRRXr8TK

and we add class on our H2 just like this : <h2 class=”exclude-toc”>introduction</h2>

but it doesn’t work, the H2 exclude still appear?

can you let me know how we input the string on the exclude heading option ?

I already search from your documentation, i only found this feature : https://tocwp.com/docs/knowledge-base/how-to-exclude-headings-by-class/ exclude heading by class, but i cannot find that option on my WordPress ?

Any help would be appreciate

Thanks
