Hi @Subgerencia and welcome to the community,
What exactly you mean change it? If you are using the native log work from Jira, then if you project/jira admin has given you sufficient rights, you can edit your worklogs.
If you are using an app, you should check if such rights exists. If they do, then you have to have something similar.
But you do have to provide a bit more information/screenshots as to what exactly you want to achieve, and where you are working on.
