Can't register different test chain.

[DedicatedDev]

{
chainID: 'chain-1',
name: 's-1',
prefix: 'test1',
rpcUrl: 'http://45.63.52.25:26657',
restUrl: 'http://45.63.52.25:1317',
denom: 'test',
},
{
chainID: 'chain-2',
name: 'sidechain-2',
prefix: 'test2',
rpcUrl: 'http://xx.xx.xx:26657',
restUrl: 'http://xx.xx.xx:1317',
denom: 'test2',
},

I want to add two chains. so-called this. it is possible only register any one chain

await keplr.experimentalSuggestChain(chainInfo);```
it doesn't trigger new chain register.
