Call add new item from another vsix extension

[m-ali-zafar]

I am creating a custom project template, in which I want to add AzureFunction, while the project is being setup. To achieve it, I first created a custom wizard. Afterwards, I found out that visual studio already provides the option to add azure function to a project with more refined options. Now I want to call, add new item wizard when my project is being setup. Is there any possible way to achieve it? Any help would be much appreciated.
