How to customize the default entry point of app on Launcher3

[13614278]

We're running Android 9.0, IMX8mini.

We want to add some default APP entry on the default Launcher. I search this on the internet, most of them said it can be customized by modifying the Launcher3/res/xml/default_workspace.xml,

But I can't find this file, I found many default_workspace_5x5.xml, default_workspace_3x3.xml, etc.

I have no idea which one should be modified, and I tried on all of these xml, none of them worked, could someone give me some help about this?
