For this current thread clarity, here is the related thread: Close Modal after record update - #18 by matthieu_chateau
Though this behaviour is quite hard to perform in Softr because it lacks stable selectors/modals are quite hard to handle with scripts. I won’t provide any feedback on this unfortunately, way too much work to do, and I doubt any solution would be stable in the future. Modals might change within the next few months.
Not native, way too sensitive to perform at scale => idea to be forgotten for the moment.
