How can I make my caps lock indicate the current input language?

After a decade on Linux, I've recently transitioned to an ARM MacBook for its convenience and user experience. On my previous Linux-powered HP, I configured the Caps Lock LED to indicate when the Bulgarian keyboard layout was active. I primarily use English and Bulgarian input languages, so having the Caps Lock LED illuminate for Bulgarian (and remain off for English) would be ideal. I've already set up my Caps Lock key to switch input languages on the Mac. Is there a straightforward method to replicate the LED behavior here? Note: I frequently use applications in full-screen mode, obscuring the top bar, which is why I prefer a visual keyboard indicator to avoid the need to switch out of full-screen to check the current language, thereby reducing typing errors. Thank you in advance!
