Sidebar Issue and Local Page Mapping

Hi,

Did you found the workout. i saw in channel, its resolved. can you update your code.

Repo readme does not work anymore

Followed your instructions, and I end up getting the following error:

(streamlit_navbar) ~/streamlit_navbar-main $ streamlit run app_navbar.py
Traceback (most recent call last):

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

I also just copied the app's code into my own newer conda env, which did work, but doesn't actually display the top bar:
