Is there a good way to fill the hole while maintaining the shape of the other parts? ?

I got mesh result from sdfstudio on ubuntu 22.04 and my pymeslab version is 2023.12

I used a neural surface reconstruction model called sdfstudio to get the mesh, but the result was a cylindrical battery-shaped object, but Pedestal under the battery was also reconstructed, so I deleted the Pedestal using meshlab.
This leaves a hole, which I would like to fill while maintaining the shape of the battery object I want, and I wonder if there is a way to do this?
If i simply fill a surface, it will not maintain its original shape and the strategic geometry will be weird.
