Checking the presence of a special meta tag in HTML code

Hey. Let me know if this feature can be implemented in Bubble: When hosted on my service, site owners must add a special meta tag to the site’s home page HTML (in the header section) to verify ownership of the site. After the site owner has placed the tag, he clicks the check button and checks for that meta tag in the site header. Is there a plugin that can check this, or is there another solution to this problem?

this cannot be done on Bubble?
