Chromium settings popup menu element

[Toptech4]

Hey everyone

I'm new to chromium Development I'm trying to add my custom element in drop-down menu of a settings and how can I link that element with my custom page.

For example if you click on settings and drop-down menu appears and then you click on downloads then a page pop-up.

It means that this page is Linked with download element

I wanted to create a page and also add an element in drop-down menu of settings. And link them.....

Any one have a idea kindly let me know Your support would be appreciated.

Thanks in advance.✌️
