Add Mega Sync folder to Pop_OS! folder list


I’d like to ask some help!
I’m kinda new in Linux and I like to add Mega Sync folder to my Pop_OS! folder list in Files, just like Google Drive does it.

Could anyone please help me, how is this possible?
Like step-by-step tutorial.

Thanks for your help in advance!

Edit: I already installed the Mega Sync app from the website, so it’s working perfectly, I just want to add the MEGA folder to the FOLDERS Sidebar (eg. Downloads, Images, Videos …).
