JavaScript to get the coordinates of a specific string within an PDF file

Is there a JavaScript solution allowing me to get the x- and y-coordinates as well as the width and the height of a specific string within a PDF file? PDF.JS can extract text chunks out of a PDF file and give the x- and y-coordinates as well as the width and the height of those chunks. But I have no influence on how these text chunks are grouped together (from single characters to larger pieces of several words) and I don't know how to address the coordinates of parts of such a chunk.

This means that if a PDF file contains "Hello world!", I would like to be able to know the x-coordinate of where "Hello" ends or where "world" starts.

Is there any way more comfortable than trying to calculate this via the width of the single characters of the given font? In Java, PDFBox allows to do so (see How to search some specific string or a word and there coordinates from a pdf document in java), but I haven't found anything comparable in JavaScript.

The reason I'm trying to do this is that I want to search for a specific text in the PDF file and find out its coordinates in order to do something with it, like drawing a rectangle around it to highlight it. Any advice on how to achieve this would be very welcome. Thank you!

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 ...
