How to change the authorization to represent the company in a 2-person General Partnership in S24?

I will briefly describe the situation as it is.
All events were conducted with the participation of the S24 portal. Together with my brother, we established a 2-person general partnership for a new business and we have equal shares. Unfortunately, due to the lack of choice, or our oversight, the option was selected when submitting to the National Court Register "EACH PARTNER HAS THE RIGHT TO REPRESENT THE COMPANY TO SUBMIT DECLARATIONS OF WILL AND SIGNATURES ON BEHALF OF THE COMPANY. TWO PARTNERS OR ONE PARTNER TOGETHER WITH A PROXY ARE AUTHORIZED". This is Section 2, heading 1 - Authorized to represent the company (attachment). I admit I didn't understand this notation before. :) As a result, it is necessary to sign all contracts by both parties, e.g. with an accounting office, setting up an account, renting an office. This is troublesome in many situations when an electronic signature is not enough to settle the matter and you have to appear in person to sign the contract. WE HAVE 100% TRUST IN EACH OTHER and we want to change this state of affairs in the National Court Register so that only one signature of any person, mine or my brother's, is enough. My question is how to do it through the S24 system? Do you have to choose a model document from the system, or can you create a letter yourself or take a resolution and send it in S24?
I will be grateful for any help. I'm ignorant of the law, especially company law, and I totally don't know how to go about it so as not to spoil it even more.

If anyone knows, I'd appreciate a step by step guide
