Device discovery when bonded devices re-connect

Is it necessary to perform the GATT device discovery process whenever two bonded device re-connect?

I'm using two nRF54L15-DK boards, one is Central and one peripheral.
Developing with nRF Connect SDK v3.3.0.

I have set it up so initially the devices are not bonded.  The first time they connect the Central automatically initiates device pairing and bonding using "Just Works".  The Central then performs Device Discovery and reads some data from the peripheral then disconnects.   There is no need to stay in a connection as the data doesn't change often.  The peripheral will wake-up, advertise and re-establish a connection maybe hours later when it has updated data. The question is, having performed device discovery on the first connection does the Central need to perform it each time the two devices re-connect?
