Direct way I can reach to solve my problem~!

I find Minecraft Education Edition so useful while using in my class,
and in this special case, I am trying to use Minecraft Bedrock Edition realm during my class. Currently, the number of realm players is limited to 10 players at the same time, but I want to increase it to 40 players. Is there any technical way that make this possible?
Also, is there any way to connect with the Xbox team? or the direct contact I can make to ask this problem?
(I've already leave help message at Minecraft Feedback but it seems that their replies are somewhat slow 😂)

Thank you so much!
