Question ProBuilder Shape Component not found

Hi, I'm trying to create a simple map of a room from a svg image of a planimetry. Through some research, I found out that I need to create an empty object, assign to it a "Probuilder Shape" and from there choose custom as the type of shape. From here, I should be able to choose an asset in the mesh editor and I should choose the svg file, which was previously imported. The problem is that when I try to add the probuilder shape component I can't find anywhere in the add component menu. If I create a new shape probuilder automatically generates a mesh for it and I can't change it. Any idea on what I have to do to assign this "Probuilder Shape" component? The plugin is up to date and the Unity version I'm using is 2021.3.20f1
