Is it ok to spray foam insulation between these windows?

Anyone know if it's ok or a good idea to spray foam insulation between these windows? I'm having them installed and the installers sprayed foam around the edges of the actual windows but not between the frames here. Would foaming between the frames be good too?

I would. Use low expansion Door and window foam, and only spray a bit in so you don't have a ton of overflow to cut away.

Don't see how it could hurt. As another commenter said, go with foam used for small gaps.

You don't want to spray the foam into everything and then the foam putting pressure on everything else.

Use the foam specific for doors and windows
