Protobuf Build Protoc select all .proto files in a directory - sh

Question

I have the following .sh file that I run to build my protos.
mkdir -p ./src/gen
protoc -I=../protos/ \
../protos/common/*.proto \
../protos/service/protos/*.proto \
../protos/ui/*.proto \
../protos/*.proto \
--js_out=import_style=commonjs,binary:./src/gen \
--grpc-web_out=import_style=commonjs+dts,mode=grpcwebtext:./src/gen
It works great, however, my team might add other directories to the protos directory that this file doesn't see.
Is there a way for me to update this script to get all .proto files in the protos directory?
I've tried the following but it didn't work:
mkdir -p ./src/gen
protoc -I=../protos/**/*.proto \
--js_out=import_style=commonjs,binary:./src/gen \
--grpc-web_out=import_style=commonjs+dts,mode=grpcwebtext:./src/gen
I'm sure it's just some syntax issue, but I'm not sure how to do it.
EDIT:
I've implemented something to make my generators more flexible, but it's still messy:
mkdir -p ./src/gen
protoc -I=../protos/ \
../protos/*.proto \
../protos/**/*.proto \
../protos/**/**/*.proto \
../protos/**/**/**/*.proto \
../protos/**/**/**/**/*.proto \
--js_out=import_style=commonjs,binary:./src/gen \
--grpc-web_out=import_style=commonjs+dts,mode=grpcwebtext:./src/gen

Since your script will pass the complete path for every file, it should be enough to add the protos/ folder with -I=../protos. The code below works fine for me, with multiple proto files in different subfolders.
$ tree ../protos
../protos
├── a
│   └── a.proto
└── b
├── b.proto
└── c
└── c.proto
$ protoc \
-I=../protos \
../protos/**/*.proto \
--js_out=import_style=commonjs,binary:./src/gen
$ tree src/gen
src/gen
├── a
│   └── a_pb.js
└── b
├── b_pb.js
└── c
└── c_pb.js
3 directories, 3 files
In your original question, you may just have mixed up ../protos/*/**.proto with ../protos/**/*.proto.
