What did you learn when you used another computer to go to that page? That is a link to this page:

If your Mac doesn't start up all the way - Apple Support

After some research, my mac does not support the update (macOS Sequoia)

You said you have a MacBook Pro (13-inch, 2020, Two Thunderbolt 3 ports). That machines supports Sequoia.

macOS Sequoia is compatible with these computers - Apple Support

Does anyone know if it is possible to update my Mac to macOS 13 so I can download Microsoft Teams? Or do i need to buy a new laptop?

According to MacTracker, your Mac can run anything between macOS 10.15..4 (Catalina) and the current version (Sequoia). It is too soon to know if it will be on the compatibility list for Sequoia's successors.

That means that it can run Ventura – or Sonoma – or Sequoia. However, you cannot downgrade macOS in place. When downgrading, you must do a "clean install" onto an erased disk.

To perform a Clean Installation of whatever version of macOS this computer Qualifies to run

Scorched Earth Method 

This method will WIPE ALL Data and there is No DATA Recovery - Period.

>> Only works on Intel Based Apple Computer <<

To perform this action will require booting from a Bootable Installer. 

The Bootable Installer can Only be performed on an Apple Computer 

This will have to be performed from a Qualifying Computer to run the version of macOS to be made on the Bootable Installer.

Example : Bootable Installer of Big Sur would have to be done on a computer that Qualifies to run Big Sur.

Notation: If the computer being used to perform this action is Too New or Too Old to qualify to run the version of macOS - this computer can’t be used.

Alternative is, to gain access to a Qualifying Apple Computer from a family member, friend or associate.
