@Haarolean I would love to contribute here, can you help me with exactly what kind of back ground styling is expected.

@pandeysambhi sure, thanks!
Here's the design: https://www.figma.com/design/IBvMpXfwbwd8d5IeOZXslK/Kafbat-UI?node-id=7193-21212&t=k0EqbLao5vn9fPwm-0

@Haarolean I analysed this quite at length and believe that the right fix would be to add the tooltip background style to theme.ts as tooltip.styled.ts is referring to theme.tooltip.bg and theme.tooltip.text.
Base theme has following values - bg: #2F3639 text:#FFFFFF and same is getting applied.
As per figma , I guess the values should be bg: #E3E6E8 text: #171A1C. let me know if sounds good and I can open the PR.
