Let me add a collapsible section here
Collapsible section headings will not appear in the table of contents in articles, even if they are formatted as H1 or H2 headers. For a header to be included in the table of contents, it must be added outside of the collapsible section. This is because headers within collapsible sections do not generate a unique URL for anchor linking purposes, which is required for inclusion in the table of contents. To ensure your headings appear in the table of contents, place them outside of any collapsible sections.
