spfx webparts – SharePoint Page URL

I have created an SPFx web part and added it to an page (eg. “abc.aspx”) in SharePoint. Then I made this page as an welcome page for my SharePoint site.

Now the URL of the welcome page is:

https://contoso.sharepoint.com/sites/Sitename/pages/abc.aspx

How can I make it to:

https://contoso.sharepoint.com/sites/Sitename
