Looking for advice fixing oak table cracks

I'm looking for advice on repairing my dining table. I have an oak dining table that has a crack running along the grain. There are three metal plates underneath the table that provide structural strength (see photo 3). After doing some youtube research, I'm unsure whether filling the crack with glue and filler is sufficient, or if I should use a bow tie joint for extra support. Any tips would be greatly appreciated. Thanks!
