Error Generating Channel Configuration and Joining Channel: Issues with Policies and Application Capability

I am experiencing an issue while generating and handling channel configurations using the Python SDK for Hyperledger Fabric. Here are the details of the problem:

1. **Error Generating Channel Transaction File**:
When trying to create a channel using the Python SDK, I receive an error related to the `configtx.yaml` configuration. The error indicates that the configuration is incorrect, specifically "no policies defined" and "could not generate default config template". The full error message is:

```
Error on outputChannelCreateTx: could not generate default config template: error parsing configuration: error adding policies to channel group: no policies defined
```

2. **Modifications Made**:
I modified the `configtx.yaml` file to define appropriate policies and permissions. The updated file is as follows (relevant part):

```yaml
Policies:
Readers:
Type: ImplicitMeta
Rule: "ANY Readers"
Writers:
Type: ImplicitMeta
Rule: "ANY Writers"
Admins:
Type: ImplicitMeta
Rule: "ANY Admins"
```

3. **Problem Joining Peers to the Channel**:
Even after modification, when the peers try to join the channel, they are being kicked out and the following error message is displayed:

```
WARNING:hfc.fabric.client:channel businesschannel not existed when join
```

**Additional Logs**:

After making the changes, when trying to join the peers to the channel, I received the following log error:

```
Traceback (most recent call last):

```

And on the node, it was logged as:

```
2024-08-17 21:17:30.155 UTC [peer] capabilitiesSupportedOrPanic -> PANI 27f [channel businesschannel] incompatible: Application capability V2_0 is required but not supported

github.com/hyperledger/fabric/core/chaincode/shim.(*Handler).triggerNextState(0xc00262d4a0, 0x0, 0xc0003ad140)
```

4. **Command Used**:
The command used to join the peers to the channel was as follows:

```python
# For operations on peers from org2.example.com, org2_admin is required as requestor
print('to make the peers of Org1 join the channel.')
responses = await cli.channel_join(
requestor=org1_admin,
channel_name='businesschannel',
peers=['peer0.org1.example.com',
'peer1.org1.example.com'],
orderer='orderer.example.com'
)

print('response from request to Org1 join to the channel: ')
print(len(responses) == 2)
```

**Expected Outcome**:

The channel should be created successfully, and the peers should be able to join the channel without errors.

**Environment**:

- **Python SDK**: `fabric-sdk-py 0.9.0`
- **Hyperledger Fabric**: Version compatible with the SDK
- **Operating System**: Ubuntu 20.04
- **Python**: 3.8

**Logs**:

The displayed error logs are as follows:

```plaintext
File "/usr/lib/python3.8/logging/__init__.py", line 929, in format
return fmt.format(record)
File "/usr/lib/python3.8/logging/__init__.py", line 668, in format
record.message = record.getMessage()
File "/usr/lib/python3.8/logging/__init__.py", line 373, in getMessage

Thank you in advance for your assistance with this issue.
