Is there a way to change file size limitations for Panel's file uploader when using Pyscript?

Question

Currently using Panel's FileInput widget in a Pyscript program, and I'm having issues with file size limitations. Per this link, it seems like there are potential ways around Panel's default file size, but it unclear how I can make that happen inside the .html Pyscript file.

They have a way via Jupyter Notebook (not applicable) and via "Server context":

# your_app.py
import panel as pn

app = ...

MAX_SIZE_MB = 150

pn.serve(
    app,
    # Increase the maximum websocket message size allowed by Bokeh
    websocket_max_message_size=MAX_SIZE_MB*1024*1014,
    # Increase the maximum buffer size allowed by Tornado
    http_server_kwargs={'max_buffer_size': MAX_SIZE_MB*1024*1014}
)

... But this code doesn't seem to work inside of the .html

Again, main goal here is to increase Panel's FileInput widget's maximum file size inside a Pyscript .html file.
