'Get only rows when column is duplicated and timestamps get a difference between them

I have to figured out how get only the rows within duplicated values but differents timestamps. Each timestamp should be between -1/+1 minutes of diff at maximum.

id client_id amount token sales_ref_id updated_at
1 29238 6.333 a$idjqb5AUdnh34 380 2020-11-17 18:45
2 2008 200 kla3@nans#9aisD 9 2020-11-17 18:45
3 2008 200 4843$a1s00c4544 9 2020-11-17 18:46
4 2008 -200 va$ie32u*Asc2001 9 2020-11-17 18:48
5 1800 6.333 a$id4843$0c45c44 19 2020-11-17 19:44

Like the data above, I should get only the rows #2 and #3, because they have the same client, amount, sales_ref_id and only have 1 minutes plus or less of difference.

But I dont have any clue how should I start to a close solution.
