Redefine certificate_vault as account owning all certificate ATAs

I tried to write it with init_if_needed like this:

#[account(
init_if_needed,
payer = payer,
associated_token::mint = output_yield_token_account.mint,
associated_token::authority = state.certificate_vault,
)]
// the account where we store all the certificates
pub certificate_vault_ata: Account<'info, TokenAccount>,

But got an error of the mint constraint has to be an account field for token initializations (not a public key). Do you know how we can convert the mint address into a mint account? Or is it ok to keep the implementation as it is now and create the certificate_vault_ata on the client side?

I think what the error is saying is that you need to pass in the mint as an account to the instruction too. So the input accounts should be:

• payer (signer of the tx, mutable)
• state
• retirement cert mint
• output yield account (the owner of the source token account) <- This should not be mutable btw
• output yield token account (the source token account - its mint must = the retirement cert mint)
• certificate vault ATA (init_if_needed, authority = state.certificate_vault, mint = retirement cert mint)
• the programs.
