Hello,
We only detect Table of Contents if you are using one of these plugins to add a table of contents section.

Unfortunately, there is no other way to look for a Table of Contents section other than to look for pre-installed ToC plugins like the ones listed above. You also use the filter provided in the above link to manually add your plugin to the compatibility list (or ask your ToC plugin provided to add it to their plugin)
You can also use this code in your theme’s functions.php file to manually tell Rank Math that you are already using a Table of Contents and to pass that test.
