I have tried extensively to change the language translation component, but I couldn't. Is there any way to do that?

You could do one thing. Hide the dropdown with CSS and put a Language icon there as a button to call the dropdown programmatically, Hope that makes sense, Let me know if you have any doubt,

[Harish-M-2003]

I'll try it and let you know
