[kombos]

Describe the bug.

using the getOfflineSigner() from the useChain() feature of cosmos-kit is leading to the error:
"Cannot read properties of undefined (reading 'client')"

Describe the steps to reproduce the behavior

The test conditions have been reproduced in the branch: testBranch1

the getOfflineSigner() is being used to get the signer in the file: data/txApi.js, in the function sendIbcTokenToMantle().
This function is being called in views/GravityToEthBridge.js file, under handleSubmit2() function.

to reproduce this error, run the dev instance of this app, go to "Bridge" main menu item, add amount value in form of 'gravity bridge' then click on "Send to Mantle Chain" button. The error log received:

Expected behavior.

the ibc transaction from gravitybridge chain to assetmantle chain, should go through without incident.
