Is there an application that shows the current layout (ru-en) next to the cursor?

Question

macOS

Greetings.
Sometimes I write and write in the wrong language, I have to erase, switch the layout and write again. I would like to see next to the cursor a translucent designation of the current language when printing. Do you know anything similar?

Worked a couple of years ago, maybe it works now.
