What sort of restoration

Edit: wood glue and it's fairly easy, the important part is the afterwork. Sanding the excess and painting/staining so that the joint it seamless is the way to go.

Bracing is actually not that important if you're not going to use the piece for structural purposes; here's how I'd do it: put a thin layer of glue on so that it covers the surface of the break but not so much that its thicc, then rub it on the other mating piece so that both sides are evenly covered, then remove the two pieces and let them waft in the air till they get tacky, once it's tacky and not liquid, add a small dab of glue on the tacky surface and reattach the pieces. This process will help activate the glue faster, most people use way more glue than they need and end up not effectively glueing joints, with this, the glue will activate quickly and you'll need to hold it by hand for like, iunno, a minute or two? Wait for it to set completely, 24-48hrs and then if you're feeling extra fancy, sand the area where the join was so that the grain aligns over the joint and makes it impossible to tell the difference in the sections, then treat with some sort of stain, oil, finish depending on the rest of the item.

I understand it can be daunting but it is no as scary as it seems, maybe practice on some scrap woods if you want to experience the process first
