Deleting app-search engines

Hey All,
I am trying to delete an app-search engine and trying to create another engine with the same name as the deleted engine but I am getting the error as 'name cannot be reused'. Can anyone tell me why is this occurring and what is the solution.

Hey there teja_sir!

Thanks for joining the community.

Are you using self-managed App Search?

If so, which version?

I am using self-managed app-search and the version is : v7.3.0
