+/**
+ * Helper to spawn a Vue dialog without having to mount it from a component
+ *
+ * @param dialog The dialog component to spawn - the component must emit the 'close' event whenever it is closed
+ * @param props Properties to pass to the dialog
+ * @param props.container Optionally pass a query selector for the dialog container element
+ * @param props.appContext Optionally the app context to use (e.g. for registered components)
+ * @param onClose Callback when the dialog is closed (parameters of the 'close' event of the dialog)
+ */
+function spawnDialog(
+	dialog: Component | AsyncComponent,
+	props: Record<string, unknown>,
+	onClose: (...rest: unknown[]) => void = () => {},
+): void;
+```
+
+## Usage
+
+The main use case is to be able to spawn a dialog from code, without the need of including the dialog component in the template.
+So a Vue dialog can be spawned in any context and not just from Vue components but also from callback functions or other API.
+
+```vue
+<template>
+	<div>
+		<NcButton @click="onSpawnDialog">🖱 click to spawn a dialog</NcButton>
+	</div>
+</template>
+
+<script>
+// Example dialog component that would be normally imported
+// Important: The dialog must emit a 'close' event whenever it is closed
+const ExampleDialog = {
+	template: `
+		<NcDialog :buttons="buttons"
+			name="Spawned dialog"
+			message="This dialog was spawned using the 'spawnDialog' function."
+			@closing="saveResult"
+			@update:open="onClose" />`,
+	components: {
+		NcDialog,
+	},
+	props: {
+		timesClicked: {
+			type: Number,
+			required: true,
+		},
+	},
+	data() {
+		return {
+			result: null,
+		}
+	},
+	computed: {
+		buttons() {
+			return [
+				{
+					label: 'Cancel',
+					callback: () => 'cancelled',
+				},
+				{
+					label: 'Accept',
+					type: 'primary',
+					callback: () => 'accepted',
+				},
+			]
+		}
+	},
+	methods: {
+		saveResult(result) {
+			this.result = result
+		},
+		onClose() {
+			this.$emit('close', this.result)
+		},
+	}
+}
+
+export default {
+	data() {
+		return {
+			timesClicked: 0,
+		}
+	},
+	methods: {
+		onSpawnDialog() {
+			this.timesClicked += 1
+			spawnDialog(
+				ExampleDialog,
+				{
+					timesClicked: this.timesClicked,
+				},
+				(result) => window.alert(`Dialog was ${result}`)
+			)
+		},
+	},
+}
+</script>
+```
