VS Code jump to next pattern

I'm learning to use Positron, an IDE built on Code OSS (the same foundation as VS Code). I want to be able to create a keybinding that jumps (without user interaction) to the next occurrence of a pattern, without further user interaction.

For instance, I believe I can trigger the "search" dialog to open, and then I type in the pattern (aka the default find). In this case, though, I want a specific hard-coded pattern so that I press the keybinding and the cursor moves immediately (with no further action).

I think the json format for keybindings.json is preferred, but if there's a more native-code method then I'm amenable. Ultimately this will be combined with other actions with

{
    "command": "runCommands",
    "args": [ "command1", "command2",...]
}

I'd prefer a native solution without extensions.

In keybindings.json:

// Place your key bindings in this file to override the defaults
[
    {
        "key": "ctrl+alt+shift+f",
        "command": "runCommands",
        "when": "editorTextFocus",
        "args": {
            "commands": [
                {
                    "command": "editor.actions.findWithArgs",
                    "args": {
                    "searchString": "fizzbuzz|fizz|buzz",
                    "isRegex": true
                    }
                },
                "editor.action.nextMatchFindAction",
                "closeFindWidget",
            ]
        }
    },
]

This "opens" the find widget, populates it, goes to the next match, then closes it. The widget never visibly opens.

Based loosely on this answer.
