How to encrypt string using Sudoku game?

Question

Encryption

An interesting option is to encrypt numbers through the Sudoku game, i.e. take the numerical sequence 167323487263826364872634, and from it get sudoku, preferably with the reverse version.
I see it as an analogue of Base64, only there the dictionary is a set of numbers and letters, and here it is some kind of Sudoku pattern, and each of the numbers is a change in this Sudoku in one direction or another.
I'm looking for at least an approximate algorithm, because in what I described above - it does not have a decryption path.
UPD**
I understand that having a numerical sequence from 1-9 that has no repetitions, in general, it is not difficult to shove a message of 9 numbers, but if we have it has repetitions? namely, 2 numbers in a row, then in this case the sudoku is unsolvable, or if the numbers come in groups of 123 **** 123, then this leads to the absence of a sudoku solution. That's why I thought that you need to have a ready-made Sudoku, and influence it with input values, then the Sudoku will somehow change (according to logical laws), but the downside is that the longer the message, the more difficult it is to return it.
