How to make the iframe link provided in Apache Superset, only load once when introducing multiple js?

I am having a problem now, I am using the link provided in the chart page of Apache Superset, the content is iframe, when I introduce multiple charts in my web project, I find duplicate loading / Static/assets/dist/explore.31a5ac0d241c9667d5a2.entry.js This js file, now I don't know how to make the whole web project load only once, /static/assets/dist/explore.31a5ac0d241c9667d5a2.entry.js The file I found is very large now, there is 56M so big, how can I reduce it.
