Re: Role for Saving Templates
Hi audrieg,
Generally there is no restriction regarding Microsoft Flow template submit, and no require of the Admin Role. We could submit the template, but whether it would be available under Microsoft Flow Gallery, depends on the approval from Microsoft.
If you have any further concerns regarding Microsoft Flow template, please feel free to post back.
The Submit to Gallery would be available after we finished New Flow creation:

The submit to Gallery won't be listed as an option unless there are customizations differ from available template.
If you have any further questions, please feel free to post back.
Regards
