I just checked Helm for the 2023 Service Manual and it does not show any printed or electronic version. They have in the past made manuals available and just as quickly pull them. GM is very reluctant to put this info out there beyond their own propiertary website which of course if you pay then you can access. For the OP the best course at the moment is to use ALLdata, which currently only goes up to 2022. Most of the information is culled from the GM source and you also get both hyperlinking which the paper copy does not do and the Full TSBs. I am using this until Helm makes available the electronic version, on jumpdrive which is considerable lighter than the 11 books that the current FSM would be.
