I’ll add that if you need/want “RPA Tool with a User Interface which allows users to Drag&Drop their scenarios” there is significant effort to bring together Camunda and Robot Framework. Camunda has been described as ‘a collection of “open source workflow and decision automation tools [to] enable thousands of developers to automate business processes and gain the agility, visibility and scale that is needed to achieve digital transformation”’ and along with it’s modeler which is desktop UI application for drag and drop workflows.
