tap the url

[minecraft://?addExternalServer=Meow Server|meow.mcpe.tw:19132|minecraft://?addExternalServer=Meow%20Server|meow.mcpe.tw:19132]

then opened the Minecraft - Friends  or not Minecraft - Servers

Further, it would be perfect if the server could be opened automatically.
For example, clicking on this link allows players to enter the server directly with one click.
