How can I update the primary_sale_happened property in Solana NFT, using python?

Question

I'm using the Metaplex python-api (https://github.com/metaplex-foundation/python-api) to update an existing NFT.

There is the update_token_metadata function (https://github.com/metaplex-foundation/python-api/blob/441c2ba9be76962d234d7700405358c72ee1b35b/metaplex/transactions.py#L110) that enable changing many of the NFT data - but not the primary_sale_happened property.

I tried to change the update_metadata_instruction_data function, but it didn't work.

the Python API is very outdated. If you are not absolutely limited to using Python you should rather have a look at JS packages or rust crates. There is no public implementation for set_primary_sale_happened in the python API.
To set field primary_sale_happened to true a special instruction has to be called similary to e.g. the authority fields. it cannot be changed through a simple data update.

Metaboss has an implementation of how to do it in rust.
