How do I teach my huskies to share toys?

Freyja my 2 yearl old (the white one) and Max my newly adopted 1 year old huskies absolutely LOVE each other, but since Freyja has been and only child for 2 years, I've noticed that she's struggling in learning how to share her toys.

Max grabbed Freyja's tug toy and went straight up to her to play tug-of-war, and at first they started getting at it, but then Freyja started to "cry" and snap at Max so he would leave the toy, he did and I took the toy away from them.

When I start next semester in college, they will be home-alone for a couple hours so I really want them (specially Freyja) to learn how to share toys, so they can entretain themselves while I'm not home.

Any advice its appreciated 🥹
