Duplicated pages in SEO

Search engines see our https://www.example.io and https://www.example.io/ as different pages (one is without slash at the end of the link, another is with a slash) If we don’t explicitly tell Google which URL is canonical, Google will make the choice for us, or might consider them both of equal weight, which might lead to unwanted behavior.
How to consolidate duplicate URLs in Webflow?

P.S. We received a notice:Rest assured that for your root URL specifically, https://www.example.io equivalent to https://www.example…io/ We recommend that you use a server-side 301 redirect.
This is the best way to ensure that users and search engines are directed to the correct page.
The 301 status code means that a page has permanently moved to a new location.https://www.example.io/ = use a server-side 301 redirect > https://www.example.io
Does it possible to do this redirect?
