how to add a mesh of prefab in Mesh Filter menu

hi guys,

I am a beginner with Unity (my second day) hence please be patient with me.

I am trying to connect a robotic project with Unity but I am encountering problems only with Mesh Filter menu.

When I try to select the mesh of my project using the drop-down menu of Mesh section, it shows only meshes of simple objects that come with Unity and not the mesh of my project.

I can see that in the pan Project there is this folder Meshes inside of folder Assets that contains an object. I cannot see this object in the drop-down menu of Mesh section.

Cloud you please help me with problem.

I thank you in advance for your support and understanding.

Cheers

should I change any of the scripts with something as follows:

public ReachyController reachy;


MeshFilter meshfilter = reachy.AddComponent();
meshfilter.mesh = reachy.GetComponent().mesh;
meshfilter.reachy.AddComponent();
Destroy(reachy);

thank you in advance for your support and understanding.

Cheers
