read matlab data

[pz16]

Hello,
I have some data stored in a matab file (data.mat). The data is stored in a table as shown in the following figure (screen shot from matlab).
   
I use the following python code to read in the mat-file:

import scipy.io as spio
lib = spio.loadmat('data.mat')
lib

Output:
{'__header__': b'MATLAB 5.0 MAT-file, Platform: PCWIN64, Created on: Fri Oct  6 18:07:57 2023',
 '__version__': '1.0',
 '__globals__': [],
 'None': MatlabOpaque([(b'data_test', b'MCOS', b'table', array([[3707764736],
                      [         2],
                      [         1],
                      [         1],
                      [         1],
                      [         2]], dtype=uint32))                  ],
              dtype=[('s0', 'O'), ('s1', 'O'), ('s2', 'O'), ('arr', 'O')]),
 '__function_workspace__': array([[ 0,  1, 73, ...,  0,  0,  0]], dtype=uint8)}

data_1=lib['__function_workspace__'][0]
data_1

Output:
array([ 0,  1, 73, ...,  0,  0,  0], dtype=uint8)

len(data_1)

Output:
16056

When I read in the mat-file, I get a single vector, which makes no sense to me. Does anyone have an example of how to read in matlab files? I have attached table in the zip-file.

The mat-file is stored with Matlab version 9.7.0.1190202 (R2019b)
