ESP-MESH with Sleep

[Alekos2313]

Hello all,
From reading the documentation, I understand , that on an ESP-MESH network, if one device -intermediate or leaf node- goes to (deep) sleep, it is actually getting "lost" from the mesh, so at wake-up, it needs to re-join as if it was just powered up. To make it clear I am considering a long time deep sleep, not few millisec, but tenths of minutes.
Is what I understood correct? and if so, is there a way, maybe by configuring some timeout?, to make the mesh stack tolerate sleeping nodes, without wiping them out?

Thanks,
Alex
