Excel, How to use "OFFSET" on the result of a "MAKEARRAY"

I generate a matrix with "MAKEARRAY" and I would like to be able to recover a submatrix of this matrix. I was thinking of using "OFFSET" but apparently it only works on range or cell.

I tried this :

=LET(data;MAKEARRAY(2;2;LAMBDA(row;col;row+col));OFFSET(data;;;1;1))

But i get "#value" as a result (this is rather normal because we cannot use OFFSET with a matrix) Offset Documentation

Another solution using the INDEX function:

Semi-colon convention:

=LET(
   array; A1:B4; row_offset; 1; col_offset; 1; 
   IFERROR(
     INDEX(
       array; 
       row_offset + SEQUENCE(ROWS(array)); 
       col_offset + SEQUENCE(1; COLUMNS(array))
     );""
   )
 )

Comma convention:

=LET(
   array, A1:B4, row_offset, 1, col_offset, 1, 
   IFERROR(
     INDEX(
       array, 
       row_offset + SEQUENCE(ROWS(array)), 
       col_offset + SEQUENCE(1, COLUMNS(array))
     ),""
   )
 )
