Apparently not. From the OP's article:
""Regarding the need for such guidance, the president offered the example of Texan Hannah Allen, who, in 2018, as an eighth grader, organized a gathering during lunch to pray for a former classmate who had been injured in an accident.
The school principal stepped in and prevented the students from praying, telling them they could only do so if it was out of sight of others in the school. The school later relented after the religious freedom group First Liberty intervened."
