C++2a features are available since GCC 8. To enable C++2a - support, add the command-line parameter -std=3Dc++2a + support, add the command-line parameter -std=3Dc++20 + (use -std=3Dc++2a in GCC 9 and earlier) to your g++ command line. Or, to enable GNU extensions in addition to C++2a features, add -std=3Dgnu++2a.
