If you have been using the legacy developer tools for a long time and don't like change, I've forked the open source projects making up the tools and am hosting them here: https://devtools.mypureinsights.com/
This is not a Genesys product, you should not ask Genesys for help with it and they maintain no liability if you use this tool. This tool has no roadmap, if you are looking for new features and innovation I recommend the officially supported Genesys Cloud dev tools https://developer.genesys.cloud/devapps/api-explorer-standalone
