While most testers apparently tests web, there’s more to testing and automation tools than web and API tools (30 Days of Automation Testing Day 9 - Find, use and share your thoughts on an API testing tool).
For desktop and commercials off-the-shelf products like SAP, SalesForce, Dynamics hooking into the application code is not feasible, so these testing contexts often require different tools than web only projects. For this Robot Process Automation tools (https://dojo.ministryoftesting.com/dojo/lessons/rpa-as-a-power-tool-for-testing) might be more handy along with more enterprise oriented tools like Tosca, Panaya Autonomous Testing for SAP etc. These tools perhaps mostly for on the testing (done by the business, not the testers) - YMMV.
