You can create a new node when you drop the connection line on the pane by using the onConnectionStart and onConnectionStop handlers.
<script lang="ts">
import { SvelteFlowProvider } from '@xyflow/svelte';
import Flow from './Flow.svelte';
</script>
<!-- You need the SvelteFlowProvider so you can useSvelteFlow -->
<SvelteFlowProvider>
<Flow />
