Style path details of KML file

Hello,

I uploaded a KML file as a file layer.
It will be displayed to me in the frontend.
Now I wanted under "path details" change the line thickness and also set a transparent background.
It does not work correctly.
Although I set the line weight to "1", we have a strength of "3" and the background is not transparent.

I tried to edit the KML file directly, but my changes are not displayed. I can only change the name of the placemark.

The KML file in an SVG file in the source code?
The thing I see is this:
<path class="leaflet-interactive" stroke="#FF00ff" stroke-opacity="1" stroke-width="3" stroke-linecap="round" stroke-linejoin="round" fill="#FF00ff" fill-opacity="0.2" fill-rule="evenodd" d="M565 40L565 9L595 9L595 40z"></path>

But I can not change the style, because they are right there in the TAG.

What can I do?

many Greetings

Hi.
Now you can apply color and opacity from paths details to your KML.
I'll add Weight, Fill Color, Fill Opacity in next release.
As for background I can't understand you. What it is?

Hi,
good job! It works.

many Greetings
