To add multiple columns in csv file

Hi Guys,

Can you help to add static values at the end of the csv file with headers

input_file
id,name
1,neo
2,pull

Expected
id,name,status,entry,g_id
1,neo,done,2019-11-01T07:14:23,pass
2,pull,done,2019-11-01T07:14:23,pass

My try but not able replacing properly and unable to achieve for adding another columns

awk '{printf "%s", $0 "\done\n"}' input_file
$ cat file
id,name
1,neo
2,pull

$ awk 'BEGIN{FS=OFS=","}{print $0,( NR==1 ? "status" OFS "entry" OFS "g_id" : "done" OFS "2019-11-01T07:14:23" OFS "pass")}' file
id,name,status,entry,g_id
1,neo,done,2019-11-01T07:14:23,pass
2,pull,done,2019-11-01T07:14:23,pass
