Changing fonts in Dynalist desktop windows APP

❓Help
1

I want to change fonts in windows desktop app by CSS.
I tried the code below and it doesn’t work. However, it works in the dynalist browser, so I want to see what’s wrong.

.Node-renderedContent,
.Node-contentContainer,
.Node-content,
textarea.node-inline-item {
font-family: “LINESeedSansKR”, sans-serif !important;
font-style: normal !important;
}

.Node-renderedNote,
.node-note,
textarea.node-note {
font-family: “LINESeedSansKR”, sans-serif !important;
font-style: italic !important;
}

Thanks!
