How to file a performance order lawsuit against a company and its managers?

A civil company that I had dealings with has 2 partners. Each partner is also the manager of the company.

The civil company had sent me a statement of account and a letter acknowledging a debt. They confirmed in writing that they will pay me AED 153,500 on 10th September 2021.

The letter is on the company's letterhead and has the sign of one of the two managers/partners of the company.

They did not pay me till now.

I wish to register a Payment Order/Performance Order (Amr Al Arida) lawsuit against the company since my right is unconditionally confirmed in writing.

QUESTION: Should I make the lawsuit only against the civil company as respondent, or should I also mention the two managers/partners as respondents i.e. a total of 3 respondents?

Please guide me.

Thank you.
