Furigana display on Japanese language posts

[SeleDreams]

Hi,
For context I am a French speaking individual who often uses Misskey instances to interact with Japanese people.
I am learning the language but my Kanji knowledge is still lackluster so it's still complicated to read some posts without copy pasting them in a dictionary.
There are some browser extensions that allow to display furigana, but they struggle with misskey because the timeline constantly gets updated. it's not a static site.
I think it would be very useful if a setting could be added to add furigana on japanese posts.
Best regards

フランス語の練習頑張ってください😊

ありがとう、でも日本語を勉強しています。フランス語じゃない。フランス語はもう喋れるから。フランス人ですからね

Sorry, I see. I'm Japanese and I'm currently studying English, so I'm not very good at reading yet. Let's both do our best.😉

Hello! Could you tell me what extension do you use?
I will try to research them :3
I might able to make extension for furigana supporting misskey!

[SeleDreams]

I tried various extensions, but either they don't work on dynamic sites like misskey, either they require to select the individual post we want to add furigana to everytime.
there doesn't seem to be one that automatically adds furigana to every misskey instance post shown on screen (I mostly am on the voskey instance)

@SeleDreams Please tell me the extension names that you tried!
then I can use them as reference how to show furigana, something like.
