Comment (by westonruter):

 @poojapadamad I think the the test you did from the Site Editor did wasn't
 correct:

 > From Styles:
 > Activate the Twenty Twenty-Five theme.
 > Go to Appearance > Editor >Styles >Blocks > Code
 > Go to the Additional CSS section.
 > Add a CSS:p { color: red; }
 > Observe the preview panel.

 Note that you tried to add a style rule targeting the `P` tag to the
 ''Code'' block. Specifically, instead of going to "Appearance > Editor >
 Styles >Blocks > Code" you should have gone to "Appearance > Editor >
 Styles > Additional CSS".
