Fairphone 4 stuck in fastboot mode after /e/OS install – not detected by Minimal ADB

/e/ Documentation had a whole set of useful pages on Windows drivers like this one with title Manual installation of fastboot driver for fp4, all currently not found https://doc.e.foundation/pages/install_easy_installer/win_fp4#solution-2-manual-installation-of-fastboot-driver-for-fp4 presumably moved off-line as they were within Easy Installer group of pages. Perhaps they could be reinstated under as eosInstaller pages.
