Expect MS Teams open SP Quicklinks within Teams, not open new browser.

Hi,

I have a SP HomePage, which is added as a tab in Teams.

That SP HomePage contains Quicklinks Webpart which has some links to SP Pages (***) (these pages in the same site with the HomePage).
Example /sites/[MySiteName]/SitePages/Games.aspx

However, when clicking these quicklinks, they open in the web browser.
But I expect to open that link within MS Teams, so that user will not navigate to new web browser. 

As I see, If I click some News on SP HomePage, it can open the news in MS Teams, without opening web browser. What is the different here, because News and SP Pages (***) are in the same Site folder:

/sites/[MySiteName]/SitePages/

Please help on this.

Thank you.
