Hi HN,We are simplifying and rationalising a set of 30-ish rather complex (finance) processes. Currently the rules and logic are all-over-the-place, specifically in ESBs, chucks of java & low-code applications and otherwise. This scattering of logic makes it expensive to change, hard to test and even more difficult to track errors. Add to that, not all steps are automated / exposed, resulting in customers calling to get updates.The plan is to consolidate as much as possible into a set of well-designed REST APIs, and use simple cloud based flow tools (for instance AWS Step functions) to codify the rules.However, some steps will require manual tasks; either to handle an error case, check the status or provide some input that can't (yet) be automated.What would be your choose for toolkit/framework to build the UIs for our internal employees?We are moving towards a JS/React set-up, so perhaps there is a nice library there or we should go full custom build, but I'm open for all - inc. SAAS or other FW / tool / builder suggestions.Many thanks
