How do I use asyncio to offload task in a discord bot?

I'm creating a discord bot where one of the commands (I'll call it long_method()) creates a call to the Youtube API and downloads comments. This takes a while and I want my bot to continue responding to other commands (short_method(), for example) while the comments are downloading.

Using asyncio, the definitions of my methods look like this:

@commands.command()async def long_method(self, ctx, params):    await ctx.send("starting long method")    loop = asyncio.get_event_loop()    loop.create_task(self.long_method_helper(ctx, params))async def long_method_helper(self, ctx, params):    # download youtube comments    # ...    await ctx.send("long method complete")@commands.command()async def short_method(self, ctx):    await ctx.send("short method called")

However, when I send the following to the discord channel, without waiting for the long method to finish:

+long_method+short_method

The bot outputs:

long method started[ takes time to process long method ]long method finishedshort method called

Instead, I want it to output:

long method startedshort method called[ time to process long method or responses to other methods]long method finished

Is there something I'm missing? Shouldn't the call to create_task(self.long_method_helper(ctx, params)) make it run in the background? Thanks!

Edit: the contents of long_method_helper:

    async def search_yt_helper(self, query, confirmation_ctx):                # get video ids and titles from Comments package        video_ids, video_titles, channels = await Comments.youtube_search_keyword(self.api_key, query, max_results=5)        n = 0        new_comments = pd.DataFrame()        logging.info(f"got {len(video_ids)} results")        # for each video, get comments from id and add them to new_comments dataframe        for v_id in video_ids:            c = await Comments.youtube_get_comments(self.api_key, v_id, scrolls=3)            n += len(c)            temp = pd.DataFrame(c, columns=['comment'])            new_comments = pd.concat([new_comments, temp], ignore_index=True)        self.comments = pd.concat([new_comments, self.comments], ignore_index=True)        ctx.send(f"added {n} comments from query")

where Comments.youtube_search_keyword() is defined as:

youtube = build("youtube", "v3", developerKey=config.youtube_api_key)    search_keyword = youtube.search().list(q=query, part="id, snippet",                                           maxResults=max_results).execute()    results = search_keyword.get("items", [])    titles = []    ids = []    channels = []    for result in results:        if result['id']['kind'] == "youtube#video":            ids.append(result['id']['videoId'])            titles.append(result["snippet"]["title"])            channels.append(result["snippet"]["channelTitle"])    return ids, titles, channels

and Comments.youtube_get_comments() is implemented similarly
