Dual Wan Setup - Help

Hi guys, I have the Mikrotic hap lite with RouterOS v6.43.16

I have spent hours on youtube and forums for a guide on setting up 2 or more wan ports for load balancing.

Every guide I see mentions changing the master port but this is no longer an option as of OS 6.4X I see.

I gather it is something about a bridge but still stuck here , is there noob / networking novice guide out there ?

Thank you in advance

You searched everywhere except in the wiki i guess.
You can start from the example here :

Recommend the first step is to upgrade the firmware version on the router.
