Make mastodon verification work with public link on profile page

I saw some days ago that nextcloud has a profile page and that you can display different social media and contact information there. That is great! I have a super small enhancement request. Mastodon has a verification process, where when you link a page to your profile it searches for the mastodon profile url on that page. If it finds the link there it displays the page as verified. More information on that here: https://joinmastodon.org/en/verification

With the nextcloud profile that doesn't work yet. The missing piece is rel="me" in the a-tag. If you would add that the page should be displayed as verified in mastodon.
