Zephyr SDK and OpenOCD on Mac (intel)

Trying again to resolve issue with uploading firmware of Zephyr SDK example to a SWAN via OpenOCD and STLink V3. I notice this error after Zephyr build within the container and wonder if the source of the issue and how to resolve?

[{
	"resource": "/workspaces/note-zephyr/src/main.c",
	"owner": "C/C++: IntelliSense",
	"code": "1696",
	"severity": 8,
	"message": "cannot open source file \"zephyr/drivers/gpio.h\"",
	"source": "C/C++",
	"startLineNumber": 11,
	"startColumn": 1,
	"endLineNumber": 11,
	"endColumn": 33
}]

Snippet from “main.c”, #include <zephyr/drivers/gpio.h> is marked as error:

// Include Zephyr Headers
#include <zephyr/drivers/gpio.h>
#include <zephyr/kernel.h>

Additional symptom. Upon deleting Container, Images, Volumes and reloading and reopening the Docker Container, a CMake error occurs related to Board Definition?
