Agreed. Postman is a classic victim of "Enshittification" to try to recoup the VC money.
I prefer this VS Code plugin for the very simple stuff https://marketplace.visualstudio.com/items?itemName=humao.re...
I'm sure there's a gap for a "better postman" that's more complex that that, but a lot less encrusted than postman.
However IMHO, the more complex scripted testing is better done in your main dev language
