A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
You're banging on the wrong door, your problem is with a university or education account, so the support for these is always done by either the university itself or whatever IT Support they've contracted with to perform this.
You should be looking on your university's website relating to the IT Support Help Desk for the apps they provide, specifically anything that mentions the use of MFA or similar authentication options which explains how to contact them for aid in resetting your authentication options in order to allow you to set them up again.
No one here is able to make changes to accounts or provide other direct support within the Microsoft account systems anyway, so only those truly inside the Microsoft Support structure could possibly do this, but not for a work or school account in any case.
Unfortunately, since you're currently located not only out of the country, but also in a country that's on the list of countries Microsoft doesn't do business with, even if this type of support were possible, which it isn't for reasons already mentioned, they couldn't provide support to someone located in such a country. The following is an example listing these countries specifically for a Microsoft 365 license, but they're all really unsupported by Microsoft for any product including account support.
"Customers that purchase Microsoft 365 may assign a Microsoft 365 license, respectively, to a user that resides anywhere in the world, except for Cuba, Iran, Democratic People’s Republic of Korea, Sudan, and Syria."
