How to let VS CODE print std::string of libc++?

Environment

• OS and Version: windows 10
• VS Code Version: 1.89.1
• C/C++ Extension Version: libc++
• If using SSH remote, specify OS of remote machine: 5.10.16.3-microsoft-standard-WSL2

Bug Summary and Steps to Reproduce

I use libc++ as following:
https://libcxx.llvm.org/UsingLibcxx.html#gdb-pretty-printers-for-libc

GDB Pretty printers for libc++¶
GDB does not support pretty-printing of libc++ symbols by default. However, libc++ does provide pretty-printers itself. Those can be used as:

$ gdb -ex "source /utils/gdb/libcxx/printers.py"
-ex "python register_libcxx_printer_loader()"

then I can print string or vector in linux in gdb, and I can print it ok aslo in vsocde in debuger console as following:

-exec p request_body
$1 = (const std::__1::string &) @0x7ffff3eebc48: ""

But I put the mouse on the variable of the code, and the original data will still be displayed.

std::__1::__basic_string_common (base):
std::__1::__basic_string_common

No response

Start with the launch.json setupCommands and the libcxx/printers.py configuration described in the issue. Compare the working GDB debug-console output with the variable hover display in VS Code. Done means determining why the hover still exposes libc++ internals and documenting or correcting the relevant behavior.
