But who do you think trained the ugandan cyber-surveillance team in the first place?

You can piece it together from the article: They had pegasus and were trained by the israeli company (probably not an advanced version... the one that just parses unencrypted comms). But they even said it was simplistic and needed/wanted more. Of course Huawei trained them. When they were unable to "punch" through with the "pegasus-style" spyware themselves, they strolled up to their teachers and said help us senpai.
