Photo Express Plugin abandoned?

I have been using Photo Express and its former version for a number of years now. Seen that it has not been updated for a long time I start worrying that the plugin may be abandoned. With the new Gutenberg around the corner I fear I won’t be able to use my google Photos in my posts any longer, as Photo Express as it is now won’t work with Gutenberg.
If this plugin is abandoned, does anyone know of an alternative?
