How to install PyQt5 version >= 5.15

How to install version 5.15 or higher version of PyQt5?
Since PyQtGraph v0.13.1 requires Qt version 5.15 at least, I definitely need this.

I installed PyQt5 using sudo apt install python3-pyqt5 command, but it installs an older version (5.12.8).

min@ubuntu-jetson:~/Desktop$ python
Python 3.8.10 (default, Jun 22 2022, 20:18:18) 
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from PyQt5.QtCore import QT_VERSION_STR, PYQT_VERSION_STR
>>> print(f'QtVer: {QT_VERSION_STR}, PyQtVer: {PYQT_VERSION_STR}')
QtVer: 5.12.8, PyQtVer: 5.14.1

And my jetson’s environment information is as follows:

NVIDIA Jetson AGX Orin
 L4T 35.1.0 [ JetPack 5.0.2 ]
   Ubuntu 20.04.5 LTS
   Kernel Version: 5.10.104-tegra
 CUDA 11.4.239
   CUDA Architecture: NONE
 OpenCV version: 4.5.4
   OpenCV Cuda: NO
 Vision Works: NOT_INSTALLED
 VPI: 2.1.6
 Vulcan: 1.3.203

Any help would be appreciated.

This would need other users to check and share experience.
