     *     at the end after reading is done.
     * @param array<string|int,mixed> $params An array of parameters to make

     *     Variable names are array keys, and variable values are array values.

     *     processed in chunks, each with

     *     numeric array key and the variable name as the array value
     *     (that is casted to a string).
     *     Note that the script's (generated) name is always added as the
     *     variable "_", which will be inadvertently lost if you overwrite it
     *     from here.
     * @param string|null             $policy Allows you to specify a policy the
     *     script must follow. Has the same format as in terminal.
     *     If left NULL, the script has no restrictions beyond those imposed by
     *     the username.
     * @param string|null             $name   The script is executed after being
     *     saved in "/system script" and is removed after execution.
     *     If this argument is left NULL, a random string,
     *     prefixed with the computer's name, is generated and used
     *     as the script's name.

     *     you can specify your own name instead.
