Running commands in cutscene context

Is it possible to execute a command from a cutscene?
It'd be useful to apply effects and affect world during the cutscene.
E.g.
```
  "effects": [
    {
      "type": "cutscenes:run_command",
      "command": "execute at @s run summon minecraft:lightning_bolt"
    }
```

If it's impossible, could I suggest implementing this?
I can even make a PR if you are busy.
