How can I add a new alias to my email in mail (iOS 13.3.1)

Hello Community,

On the past I had my 2 email aliases setup to my email in mail app.

I didn't use any email alias for the past 6 months and now I want to add 2 aliases to my office365 email in "Apple Mail App" on my iOS 13.3.1.

Could you please provide me with the solution?

Outlook in iOS for me is not a solution!

Thanks
