How to fill a shell hole 1

[SofiaB]

Hello everyone,
I have a 3D shell truss that as a chord with a hole used to pass a brace. Since now I want to remove that brace from the chord I'm left with a hole. Does anyone know an easy geometry property that I can use to fill that hole? I'll leave an image for better understanding.

Thank you in advance for the help.

For this purpose you can use the Geometry Edit tools (available in the Part module) such as Face --> Remove and Face --> Cover edges.
