Convert seconds to days, hours, etc on axis labels

Question

I am trying to plot a chart which needs to have duration times in terms of "days, hours, minutes" on the Y axis and just dates on the X axis. I can do this easily if the duration is expressed in seconds but in order to improve readability I'd like to change the Y labels to be something like DTHH:MM, e.g., 1 Day(s) 10:23. Does anyone know how can this be accomplished?

This is my current code snippet:

chart = (
        alt.Chart(aggregated_df, title=metric_name_to_display)
        .mark_line(point=True)
        .encode(
            alt.X(f"yearmonthdatehours({QUERY_TIME_COLUMN_NAME}):O").title("Date"),
            alt.Y(f"{metric_name}:Q").title(metric_name_to_display),
            alt.Color("Index:N"),  # type: ignore
            alt.Tooltip(
                [metric_name, f"yearmonthdatehours({QUERY_TIME_COLUMN_NAME}):O"]
            ),
        )
    )

where aggregated_df is of the form

query_time                        recovered_seconds_all_ingest
