How to set style of text and headers in BasicRichText independent of style RichTextThemeProvider?

[SmartToolFactory]

If i set text style in textStyleProvider i'm not able to set header style, they are overridden by this style, all of them have same size and color, etc. Is there a way to set header styles and text style independent of each other?

Is there a style to set text style in BasicRichText with stringStyle?

Sample to try ti out

RichTextThemeProvider(
//            // Overrides every other style in BasicRichText
//            textStyleProvider = {
//                TextStyle.Default.copy(
//                    fontSize = 18.sp,
//                    lineHeight = 22.sp
//                )
//            },
//            textStyleBackProvider = { style, content ->
//                ProvideTextStyle(style.copy(color = Color.Red)) {
//                    Box(modifier = Modifier.border(1.dp, Color.Green).padding(8.dp)) {
//                        content()
//                    }
//                }
//            },
//            contentColorProvider = {
//                // This is Text Color
//                Color(0xffFF8F00)
//            },
//            contentColorBackProvider = { color, content ->
//                Box(modifier = Modifier.border(3.dp, Color.Red)) {
//                    content()
//                }
//            }
