Docs don't make something clear

In the example:

import {BatchScript} from "forge-safe/BatchScript.sol";

...

function run(bool send_) public {
        string memory gm = "gm";
        address greeter = 0x1111;

        bytes memory txn = abi.encodeWithSelector(
            Greeter.greet.selector,
            gm
        );
        addToBatch(greeter, 0, txn);

        executeBatch(safe, send_);
}

It is unclear whether run is an internal function inside a contract that inherits run. Could you clarify whether that is the case. Because how else are addToBatch and executeBatch being called?
