It seems that the API doesn’t support item name in activity log, it is recorded on the board but not returned in the API call:
{
boards(ids: 8967422026) {
activity_logs(
from: “2020-01-01T00:00:00Z”
to: “2026-11-03T15:46:10.391501Z”
column_ids: [“name”]
item_ids: [18073016056]
limit: 1
) {
id

}
}
}
