Text too small to read - Google Search Console Vitals - Bootstrap

Google Search Console Vitals on the Mobile Usability section says my index.html has “Text too small to read”.

I thought it was a redirect that caused it before, which I removed. Now there is no redirect. All of the text on my site is a decent size. I have a theory on what is causing this but not sure… I think it is because there are only <h6> headings on my home page and there are no <p> or regular text elements…

Any ideas how I can make Google like me? I rather not add any more text to my page as this is my design intent…
