Firebase shows following error when I try to add sha1 in firebase console for phone authentication.
To make a change, ask a project owner for necessary change
Even though, I am one of the owners. Here is the image link of error. Can anyone help ?

This error message is also shown if the SHA is already used in another project. This is indeed not at all clear from the message, so we'll get that fixed. But in the meantime, you'll have to find the other project that is using the SHA and remove it from there before adding it to this project.
