I'm looking for a way to delete all Sessions except the newest Session for each User managed by KeyCloak

Currently, I am using KeyCloak to manage sessions for application users.
However, there is a problem that KeyCloak’s memory capacity is getting high now.

Therefore, my team are considering a method to delete unnecessary sessions to allow more memory capacity.

To achieve this, we are considering the following method.
・Delete all Session except the newest Session for each user
