The sidebar does not appear unless refreshing the webpage. (Chrome, MacOS)

I am using MacOS 13.0.1.
For Chrome, the script sidebar does not appear at the first time when opening ChatGPT webpage, unless refreshing it again.
For Safari, the sidebar does not appear even I refresh many times. It is weird that whenever I refreshed the page, the sidebar flashed about 0.1s but disappeared immediately. In order to use this script, I have to restart Safari and reopen the webpage several times. I guess it is not stable enough with MacOS.

I just tried it on Safari again. I refreshed the webpage 3 times and the script sidebar appeared. However, it disappeared suddenly when refreshed for the 4th time.
