Filter based on number of characters between 2 fixed charaters

[nokoyman]

I am trying to filter the rows by the number of characters between 2 fixed characters.

123-XYZ-6548
256-A-N356
568-BBS-3569
5638-C-5213

In the sample below, I need to hide the rows that have 3 characters between the dashes (-).

Thanks for the help.
