Thanks for the explanation.
However, you can type the name of the desired page you are looking for in the search field there too: https://prnt.sc/0muT5iXlaYgo
No filter is available there, but you can still search with the page name.
About this query: "Also when you use this function to link to a page, the opened page will not show its page title."
The Page Title is not linked with the page itself but with the menu item to which it is actually assigned.

So if you link your element or addon to a page, then it will not show the page title, and now you will find it reasonable, I think. On the other hand, if you link your element or addon to a menu item that is associated with the desired page, then you will get the page along with the page title.

I hope it's a bit clearer now.
