Why is vue-notification not displaying text?

Question

Vue.js

Code on TS:

async sendRequest(ctx?: any, payload?: any) {
      const response = await requestToApi(
        "/api/login/...,
        "post",
        false,
        payload
      );
      if (response.token !== null) {
        ctx.commit("updateToken", response.token);
      } else {
        Vue.notify({
          group: "auth",
          type: "error",
          title: "No authorize",
          text: "Please sign in!"
        });
      }
    }
