We analyze an analog of the $t$-$J$-$U$ model as applied to the descriptionof a single moir\'e flat band of twisted WSe$_2$ bilayer. To take into accountthe correlation effects induced by a significant strength of the Coulombrepulsion, we use the Gutzwiller approach and compare it with the resultsobtained by the Hartree-Fock method. We discuss in detail the graduateappearance of a two dome structure of the superconducting state in the phasediagram by systematically increasing the Coulomb repulsion integral, $U$. Thetwo superconducting domes residing on both sides of a Mott insulating state canbe reproduced for a realistic parameter range in agreement with the availableexperimental data. According to our analysis the paired state has a highlyunconventional character with a mixed $d+id$ (singlet) and $p-ip$ (triplet)symmetry. Both components of the mixed paired state are of comparableamplitudes. However, as shown here, a transition between pure singlet and puretriplet pairing should be possible in the considered system by tuning the gatevoltage, which controls the magnitude of the valley-dependent spin-splitting inthe system.
