For now, Go here https://github.com/rutcreate/TextMesh-Pro-Thai.git

Add
"com.unity.textmeshpro": "https://github.com/rutcreate/TextMesh-Pro-Thai.git"
To manifest.json in your project

If you use textmeshpro then replace instead of add
Like this
"com.unity.textmeshpro": "2.1.1",
to
"com.unity.textmeshpro": "https://github.com/rutcreate/TextMesh-Pro-Thai.git",

เปลี่ยนไปใช้อันนี้เน้อว https://github.com/rutcreate/TextMesh-Pro-Thai.git

เพิ่ม
"com.unity.textmeshpro": "https://github.com/rutcreate/TextMesh-Pro-Thai.git"
ใน manifest.json ใน unity proejct นะ
