Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
You should be able to do it from Dashboard > Redirections, and the Setting button would appear.
Please see this screenshot: https://i.rankmath.com/PB3ici
Let me know if you do not see this. You can use tools like https://ibb.co/ or Loom to take a screencast and put it in the Sensitive Data section.
Looking forward to helping you.
