Sonoma: how to show the input source popup before I select a textbox and starting to type?

I am a Chinese people and I've been using English and Chinese interchangeably. So very often I will search in English in Safari, and after a second, typing a document in Chinese.

Therefore I never know whether my input method is to my expect.

It happens all the time when I will stumble typing a few Chinese Pinyin, but the input method was English, and it can't recognize Pinyin and turn them into Chinese characters, then I have to delete these few letters, switching the correct input method and type them again. Vice versa, it's the same situation when I want to type English while the system was at Chinese.

I know that I can easily check my current input method from the menu bar-control centre, but that would require a long distance of moving my eyeballs which is very disturbing when you are focus on sth as simple as typing. And I have tried this useless "Automatically switch" function, it just makes the situation even worse.

The macOS Sonoma actually provides a handy tool to show the current input method under my cursor but only when I switch input method proactively, which was not the right time for me. What I hope is that it can popup every time I select a textbox, so that I can check and change to the correct input method without losing to much attention of what I will type. And right now there isn't anyway in settings to determine when it should appear.

Great Thanks!
