Assumptions:
Generate the STM32CubeIDE project for your MCU to get Debug Configuration File for OpenOCD.
To do that, follow [Debug][Keil][STM32CubeIDE] How to debug Keil's STM32 project in STM32CubeIDE? (Part 1)
Open Keil's Project location by “Open with Code” integrated menu in Windows - the place where you have /Src, /Inc, etc.
NOTE: If you are missing "Open with Code" option in Context Menu, then reinstall VSCode and make sure that you have checked these options:
Create “launch.json” file by hitting F1 in VSCode (which corresponds to “Menu->View->Command Palette”) and start typing “launch”.
Select “Debug: Open launch.json” and then select “Cortex Debug”.
Copy-paste the following template to the newly created “launch.json”:
Mine “launch.json” looks as follows:
Hit F5 in VSCode (which corresponds to “Menu->Run->Start Debugging”) and start debugging in VSCode!
Hope it was helpful for someone there.

- STM32CubeIDE needs to be installed. At the time of writing this guide, STM32CubeIDE version is 1.6.1 Build: 9958_20210326_1446 (UTC).
OpenOCD and GDB server are already preinstalled in STM32CubeIDE, so no need to install separately; - Keil's .uvprojx project needs to be built to .elf file (generated from .axf file);
Used command:Code:fromelf.exe example_in.axf --elf --output example_out.elf" - VSCode has plugins: “C/C++” and “Cortex-Debug”.
