How to slow down speed when agent goes through offmehslink?

I created a gameobject with a offmeshlink component and it works fine but when uses offmehslink the agent increases speed and movement is unrealistic, can speed be slowed down when agen crosses the offmehslink?

 

Check out the NavMeshAgent's "isOnOffMeshLink"

 

I was already using that but there is always noticed some change of speed when going through offmeshlink. I tried using mecanim animations but does the speed, speeds up when going through

Also when going through offmeshlink walk animation doesnt work, just moves without animation

 

Check the script they added here: https://docs.unity3d.com/ScriptReference/AI.NavMeshAgent.CompleteOffMeshLink.html

it normalizes the speed when moving on the links.
