Webflow site internal link option not available

Dear webflow heroes
Our new site is being built by a local webflow expert and SEO company but I think he is missing something about internal links. Im sure I can have a dropdown to link to readily made internal pages which would include link destination description of course as the pages are already made.
I only get a dropdown for external link with not box to type link destination description.
Insites.nibbler ranks new site low on internal links 52 links have no description etc.
How can I get this option to do link from body text on a page to an existing page on the same site. There must be an option to allow this.
Thanks in advance
www.abcreative.nl is the site. All the text links are ‘external’ only option I was given by the editor. There must be an option for internal links.

Here is my site Read-Only: LINK
(how to share your site Read-Only link)

I have found the dropdown. We have 25 landing pages but not all the landing pages are listed in the dropdown. Also the 4 services are not listed only the general Services page.
Any ideas further? Maybe this is not the right place to ask these questions … is there a discord channel or something more active to get some support! Thanks for reading!

Hey @treetoplake, are you able to share the read-only link. Either way, I suspect you are looking for a Dynamic page/Collection pages. Whereas the dropdown will only show static pages.
