How display a PDF file in the same view on the right

I have a view where I have a TreeList that when clicking on the nodes I would like to display PDF files on the same view.

For this every time I click on the nodes it calls a controller sent as a parameter an ID and this returns the file currently works but opens it in another tab. What I want to do is somehow display in another panel to the right of the TreeList the documents in the view.

I leave an image for better understanding and the code below

Currently the PDF opens in another tab

enter image description here

I want to display the document on the right panel of the screen

enter image description here

View

@model ViewModels.Home.MRecords

<script>


> This function when clicking on the nodes call Controller and return PDF document.

    function onNodeClick(s, e) {
        window.location.href = '@Url.Action("GetAttachments", "Home")' + "?Id=" + e.nodeKey

    }


//Here I call to the actually Partial view where I have the TreeList.
@Html.Partial("_TreeListPartial", Model)

Controller that return PDF File

public async Task<ActionResult> GetAttachment(Guid id)
{
    var vm = new ViewModels.Home.AttachmentViewModel();
    var result = vm.GetServiceAttachment(id));

    //Function to get the file information from DB .
    
    byte[] file;
    foreach (var attachment in result)
    {
        file = attachment.File;
        byte[] byteArray = file;
        return new FileContentResult(byteArray, "application/pdf");
    }
    return null;
}

I'm only interested in knowing exactly how from the controller I can return a view or something that can be seen in the right panel of my view where I have the TreeList .

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
