Cannot find "/usr/bin/arm-none-eabi-gcc"

[keestux]

I realize that this is a simple question, but with a not so simple answer.

Since a few weeks I'm using the vscode flatpak. I need to build my software with a cross compiler, mostly arm-none-eabi-gcc. It is installed on my system, but from with vscode it cannot be found. So, my question:
How can I enable /usr/bin/arm-none-eabi-gcc and friends from vscode?

you need to install faltpak-SdkExtensions instead, but there is no "arm-none-eabi-gcc" flatpak-SdkExtension in flathub,
the same trouble with me , so I am consider downloading the vscode rpm version manually and using rpm-ostree to install it.
