cant modify diffed branches - buffer modifiable false

[scottshane]

When using the :DiffviewOpen HEAD...other_branch command in Vim, the resulting split buffers are opened in "nomodifiable" mode. This prevents commands like do, dp, diffget, and diffput from working as expected, resulting in the error "Cannot make changes, 'modifiable' is off."

Diffview is installed without any custom configuration.

Does the Diffview plugin inherently lack support for editing when diffing branches using this specific command, or is there a configuration or workaround to enable editing within the diffview?
