I’m not an expert but maybe a bit of shuttering ply at the front presuming it’s going to slump forward, a bucket and float trowel/pointing trowel.
Maybe an old brush to wet/PVA what you are going on top of.
I used mortar/SBR for holes round a window frame and mortar to build up a corner of a bathroom floor
