Hello once again. You suggested I take up this issue. Appreciate the opportunity

[dj8yfo]

@TobieTom #1283 is mechanical edit of 2 lines with added links.

This one , besides mentioning [env::attached_deposit], requires doing cargo expand on contract with and without #[payable] and potentially consulting implementation in near_sdk_macros to figure out, which [env] host functions the attribute relies (if any) on to carry out its function.
