Permission error while starting Bitwarden

I have installed self-hosted Bitwarden instance using rootless docker mode, although while trying to start it I receive:

bitwarden.sh version 1.45.2
Docker version 20.10.12, build e91ed57
Docker Compose version v2.2.3

./bitwarden.sh: line 118: /opt/bitwarden/bwdata/scripts/run.sh: Permission denied

Additional environment specs: Oracle Linux 8, SELinux in permissive mode.
I know that rootless docker is making use of newuidmap and newgidmap and in fact during installation the ownership of bwdata is changed to UID and GID mapped to my bitwarden user, but it looks like he is not really owner of the files and has no rights to execute scripts. Any ideas what am I doing wrong?
