We are currently unable to approve add-on apps in our Microsoft 365 tenant. 

We recognize that some of these tools can be valuable. However, it is not guaranteed that all add-ons are safe for our environment, even if they are developed by reputable sources with the best intentions. 

As organization-wide add-ons, these require extensive legal, technical, and possibly academic reviews to determine if significant value exists relative to the risk. We simply don't have the resources for such reviews at this time. 

We will work to develop a review process at some point in the future.
