+
+## Get Teams Apps in App Catalog
+
+Using teamsApps() you get the Teams AppCatalog
+
+```TypeScript
+import { graphfi } from "@pnp/graph";
+import "@pnp/graph/teams";
+import "@pnp/graph/appCatalog";
+
+const graph = graphfi(...);
+
+const apps = await graph.appCatalog.teamsApps();
+
+```
+## Get Teams Apps by Id
+
+Using getById() you get the Teams App by Id
+
+```TypeScript
+import { graphfi } from "@pnp/graph";
+import "@pnp/graph/teams";
+import "@pnp/graph/appCatalog";
+
+const graph = graphfi(...);
+
+const apps = await graph.appCatalog.teamsApps.getById('{teams app id}')();
+
+```
+## Add a Teams App
+
+
+```TypeScript
+import { graphfi } from "@pnp/graph";
+import "@pnp/graph/teams";
+import "@pnp/graph/appCatalog";
+
+const graph = graphfi(...);
+const appPackage = {...} as Blob;
+
+//second parameter is "Requires Approval"
+const app = await graph.appCatalog.teamsApps.getById('{teams app id}').add(appPackage, false);
+
+```
+## Update a Teams App
+
+```TypeScript
+import { graphfi } from "@pnp/graph";
+import "@pnp/graph/teams";
+import "@pnp/graph/appCatalog";
+
+const graph = graphfi(...);
+const appPackage = {...} as Blob;
+
+//second parameter is "Requires Approval"
+const app = await graph.appCatalog.teamsApps.getById('{teams app id}').update(appPackage, false);
+
+```
+## Delete a Teams App
+
+```TypeScript
+import { graphfi } from "@pnp/graph";
+import "@pnp/graph/teams";
+import "@pnp/graph/appCatalog";
+
+const graph = graphfi(...);
+
+//delete a Teams App
+await graph.appCatalog.teamsApps.getById(app).delete();
+
+// delete an un-approved Teams App requires the app definition id.
+// sample is just selecting the first app definition.
+const appDefinition = (await graph.appCatalog.teamsApps.getById("{teams app id}")()).appDefinitions[0];
+await graph.appCatalog.teamsApps.getById(app).delete(appDefinition);
+
+```
+## Get Teams App Definitions
+
+```TypeScript
+import { graphfi } from "@pnp/graph";
+import "@pnp/graph/teams";
+import "@pnp/graph/appCatalog";
+
+const graph = graphfi(...);
+
+//get teams app definitions
+await graph.appCatalog.teamsApps.getById(`{teams app id}`).appDefinitions();
+
+```
+## Get Teams App Definitions by Id
+
+```TypeScript
+import { graphfi } from "@pnp/graph";
+import "@pnp/graph/teams";
+import "@pnp/graph/appCatalog";
+
+const graph = graphfi(...);
+
+//get teams app definitions
+await graph.appCatalog.teamsApps.getById(`{teams app id}`).appDefinitions.getById(`{Teams App Definition Id}`)
+
+```
+## Get Bot associated with Teams App Definition
+
+```TypeScript
+import { graphfi } from "@pnp/graph";
+import "@pnp/graph/teams";
+import "@pnp/graph/appCatalog";
+
+const graph = graphfi(...);
+
+await graph.appCatalog.teamsApps.getById(`{teams app id}`).appDefinitions.getById(`{Teams App Definition Id}`).bot();
+
+```
