executePostMessageSent

```typescript async executePostMessageSent(message: IMessage, read: IRead, http: IHttp, persistence: IPersistence, modify: IModify): Promise { console.log(1); let stopTyping: (() => Promise) | null = null; try { const appUser = (await read.getUserReader().getAppUser())!; console.log(2); stopTyping = await modify.getNotifier().typing({ id: message.room.id, scope: TypingScope.Room, username: appUser.name, }); console.log(3); await sleep(2000); // Custom sleep funciton console.log(4); } catch (e) { console.log(5); } finally { console.log(6); await stopTyping?.(); console.log(7); } } ```

Using this.getLogger().log instead of console.log leaves no logs saved/printed. Calling modify.getNotifier().notifyUser in slash command works without errors.

Message Result must exist for success Response objects seems to be from jsonrpc-lite, called from this line.
