PLS SEND HELP! Having some trouble on rotating an object

so im using this button to control a cylinder to rotate 90degrees on every click
the problem is when i click on the button, the cylinder just jumps from 0 to 90,not showing the movements in between
can someone tell me what im doing wrong here or what i should add to make the rotation movement visible, but not just jumping from 0 to 90?

btw the pic i uploaded is not accurate, the yAngle is already set to 90
and i have 0 knowledge in coding or scripting

 

You can Lerp from 0 to 90 in some time.

This is how I lerp Velocity from 5 (MoveSpeed) to 2 in 1sec:




I need also:



It is necessary to reset the timeElasped variable when I enter into State Walking.
I use the State Graph, but you can adapt the nodes to the Flow Machine

And this is where I increment the timeElasped:




I use FixedUpdate() because I use RigidBody.MovePosition but You can use normal Update()

 

While key hold move by say 10 degz
