I need to set redirect

Im trying to do this:

https://****therapy.com/webinars/my-account/ –> https://://****therapy.com/webinars/my-account/edit-account/

this is what I’ve added to .htacess, but it’s not working

RewriteRule ^webinars/my-account/$ /webinars/my-account/edit-account/? [L,R=301]

During the chat we’ve tried a lot of different variations, but nothing helps. Please, check the intenal chat descriotion for further reference.
