Signing multisig transactions with multisig accounts as the signers

[Bhavya-cybernext]

I need to implement a 2-of-2 multisig with its signers being two 1-of-2 multisig accounts.

After obtaining the partial signatures from the signers of both the 1-of-2 multisig accounts, how to combine them to be able to submit the transaction through 2-of-2 multisig?

What i'm currently doing:
-partial sign from the 1 signers each in the 1-of-2 multisig
-wrapping these partial signatures with their respective 1-of-2 multisig signerData
-Combining the two signature infos generated in the previous step and preparing the multisigTx
-Broadcasting to the chain

What am i doing wrongly here? How to do this correctly for proper tx multisignature verification in the chain?

I really like Evmos documentation on this > can you try these steps https://docs.evmos.org/protocol/concepts/multisig
